Answer: squared

Step-by-step explanation:

Triangles ADT and EDT are congruent by SSS rule and triangles BLG and PFX are congruent by SAS rule.

In triangle ADT and EDT, we get that:

AD = DE (given)

AT = ET (given)

DT = DT (common)

So, ΔADT ≅ Δ EDT (SSS congruency rule)

In triangle BLG and PFX, we get that:

BL = PF (given)

BG = PX (given)

∠ B = ∠ P (given)

So, ΔBLG ≅ Δ PFX (SAS congruency rule)

Therefore, we get that, triangles ADT and EDT are congruent by SSS rule and triangles BLG and PFX are congruent by SAS rule.

Step-by-step explanation:

worksapce thingy

3x+17=5x-7

2x=24 x=12

no idea if im right .-.

===========================================================

Reason:

Let's check to see if choice A is the answer. We'll replace each x with -1

2x^2 + 4x = 3 + 3x^2

2(-1)^2 + 4(-1) = 3 + 3(-1)^2

2(1) + 4(-1) = 3 + 3(1)

2 - 4 = 3 + 3

-2 = 6

We don't end up with the same thing on both sides, so x = -1 is not a solution to the equation.

--------------

Now try x = 0

2x^2 + 4x = 3 + 3x^2

2(0)^2 + 4(0) = 3 + 3(0)^2

2(0) + 4(0) = 3 + 3(0)

0 = 3

That's false as well, which allows us to rule out choice B.

--------------

Next up plug x = 3 into the equation

2x^2 + 4x = 3 + 3x^2

2(3)^2 + 4(3) = 3 + 3(3)^2

2(9) + 4(3) = 3 + 3(9)

18 + 12 = 3 + 27

30 = 30

We get the same thing on both sides so we have confirmed x = 3 is a solution.

--------------

There may be other solutions. If we tried x = 6, then it leads to 96 on the left hand side and 111 on the right hand side. That rules out x = 6 as a solution.

Option A is the correct Answer a<b.

                angle a= 180-(75+75)=30°

         to confirm that a<b.

Answer:

Definition. Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles. If two or more figures have the same shape, but their sizes are different, then such objects are called similar figures.

The statement that is not true about the angles in the triangle is OPTION C. The measure of ∠K is 89°

An equation is an expression that shows the relationship between two or more numbers and variables.

Equations are classified based on degree (value of highest exponents) as linear, quadratic, cubic and so on. Variables can be dependent or independent. Dependent variables depend on other variable while an independent variable do not depend.

From the diagram:

∠J + ∠K + ∠L = 180° (angles in a triangle)

Substituting:

(7x + 2) + (8x) + (4x + 7) = 180

19x + 9 = 180

x = 9

∠J = 7x + 2 = 7(9) + 2 = 65°

∠K = 8x = 8(9) = 72°

∠L = 4x + 7 = 4(9) + 7 = 43°

∠k ≠ 89°

What is the unitary method of problem solving?
The unitary technique, in its most basic form, is used to calculate the value of a single unit from a specified multiple. The unitary approach can be used to complete it. Additionally, after determining the value of a single unit, we can multiply that value by the number of units needed to determine the value of the additional units. The concept of ratio and proportion is mostly applied using this way.

Given, for every 3 pencils, number of pens bought = 2
Therefore, every 1 pencil, number of pens bought = 2/3
Thus, for 21 pencils, number of pens bought = (2/3)*21 = 14
Therefore, total number of pencils and pens bought by Henry = 21 + 14 = 35.

Answer:

23) 30°

24) 12°

Step-by-step explanation:

23) Lines will be parallel if the co interior angles are supplementary.

               ∠3 + ∠5 = 180°

 3x+ 25 + 4x - 55 = 180

3x + 4x + 25 -55 = 180

Combine like terms,

            7x -  30    = 180

Add 30 to both sides,

                7x = 180 + 30

               7x = 210

Divide both sides by 7,

                x = 210 ÷ 7

                x = 30

24)    If the lines are parallel, then the alternate interior angles are congruent.

                  ∠7 = ∠2

           11x - 36 = 8x

Add 36 to both sides,

                 11x   = 8x + 36

Subtract 8x from both sides,

          11x - 8x  = 36

                  3x = 36

                    x = 36 ÷ 3

x = 12°

The multiplication expressions shown by the model are:

A multiplication expression is a mathematical statement that uses the multiplication operand with either number, variables, or a combination of the two to produce results.

The numbers or variables in a multiplication expression are known as multiplicand (the first number to be multiplied) and multiplier (the second number multiplying).

The result or solution of a multiplication operation is known as the product.

Thus, other possible multiplication expressions can be written out from the model because of the additive property of multiplication.

The question tests on probability and combinations.

To obtain the probability for selecting exactly two red and 5 white urns is:

If Wi and Ri are events for selecting the ith ball, apply the multiplicative rule to obtain:

=P(W1∩W2∩W3∩W4∩W5∩R1∩R2)

= P(W1)P(W2|W1)P(W3|W1∩W2)P(W4|W1∩W2∩W3)P(W5|W1∩W2∩W3∩ W4)P(R1|W1∩W2∩W3∩W4∩W5)P(R2|W1∩W2∩W3∩W4∩W5∩R1)

=6/10×5/9×4/8×3/7×2/6×4/5×3/4

= 1/10

The probability is 1/10.

Alternatively, use the Bayes theorem. This uses combinations. To get the probability for exactly 5 white and 2 red, obtain the chance for selecting 5 white balls and 2 red balls; 6C5 and 4C2.

(6C5×4C2)/10C7 = 6×6/120 = 1/10

The probability for at least 5 balls is obtained by the probability of either selecting 5 or 6 balls.

Using combination;

(6C6 X6C5)/10C7 = (1x6)/120 = 6/120 = 1/20.

Considering the definition of a line, you get:

A linear equation o line can be expressed in the form y = mx + b

where

In this case, you know:

Substituting the value of the slope m and the value of the point in the expression of a linear equation, y = mx + b, the value of the ordinate to the origin b can be obtained:

-4= 1/2×0 + b

-4= 0 + b

-4 = b

Finally, the equation of the line is y= 1/2x -4.

In this case, you know:

Substituting the value of the slope m and the value of the point in the expression of a linear equation, y = mx + b, the value of the ordinate to the origin b can be obtained:

2= 1/2×(-5) + b

2= -5/2 + b

2 + 5/2= b

9/2 = b

Finally, the equation of the line is y= 1/2x +9/2.

Knowing two points (x₁, y₁) and (x₂, y₂) of a line, the slope m of said line can be calculated using the following expression:

m= (y₂ - y₁)÷ (x₂ - x₁)

Substituting the value of the slope m and the value of one of the points in the expression of a linear equation, y = mx + b, the value of the ordinate to the origin b can be obtained.

Being (x₁, y₁)= (2,0) [x-intercept] and (x₂, y₂)= (0,8) [y-intercept] , the slope m can be calculated as:

m= (y₂ - y₁)÷ (x₂ - x₁)

m= (8- 0)÷ (0 -2)

m= 8÷ (-2)

m= -4

Considering point 2 and the slope m, you obtain:

8= -4×0 + b

8= 0 +b

8=b

Answer:

Describe how anthropology challenges more commonly held notions of progress

Step-by-step explanation:

Answer:

f(-10) = -299999

Step-by-step explanation:

Equation

f(x)= −3x^55+1

Given

x = - 10

Solution

You have to understand what f(x) means. When you put a value in for x, every x on the right is supplied with that value.

In this case I take the equation to mean what ever we are given in the brackets (in this case 10) is what goes into the x on the right. So the new equation is

f(-10) = -3*(-10)^5 + 1

(- 10) ^5 = - 100000

f(-10) = -300000 + 1

f(-10) = -299999

Sterling is also fourth-most-held reserve currency in the world's reserves as of mid-2021.

Let X equal  number of small boxes

Let Y equal number of big boxes

The first equation is:  X + Y =  24     ( this shows that total number of boxes = 24)

The second equation is:    45X + 75Y  = 1410    ( this is because small box weighs 24 pounds and big box weighs 75 pounds.  The total weight of small boxes is 45 times weight of each individual box. And the total weight of second boxes is equal to 75Y.
