Answer:

B. 5a² + 3b + 6a

Step-By-Step Explanation:

First, see what has like terms. 7a² and -2a² both have the exponent 2 and the letter a, so you can combine those to get 5a². 3b and 6a cannot be combined because they have a different letter. So, 5a² + 3b + 6a is your answer.

ANSWER:

64 square inches.

STEP-BY-STEP EXPLANATION:

The first thing is to calculate the ratio between the corresponding sides of the triangles:

We must bear in mind that the area of the larger t triangle is equal to the area of the small triangle multiplied by the ratio of the square, since the area is a quadratic unit, therefore:

The area of the larger triangle is 64 square inches.

Answer:

Step-by-step explanation:

you have a 1/6 of rolling a certain number on a regular die.

if you try to get 5 or 6 you have a 2/6 chance of rolling either of them

if you try to evens you have a 3/6 chance of rolling 2,6, or 4

The system of linear equations and their solutions are:

1. (51, 26):  x - y = 25; 2x + 3y = 180

2. (-17, -36): x - y = 19; -2x + y/6 = 28

3. (47, 33): 2x - 3y = -5; x + y/11 = 50

4. (-31, -56): 2x - y = -6; x - 305/3 = 2y.

We can solve a system using the substitution method by finding the value of one of the variables, followed by substitution.

1. x - y = 25 -- eqn. 1

2x + 3y = 180 -- eqn. 2

Rewrite eqn. 1:

x = 25 + y

Substitute x = 25 + y into eqn. 2:

2(25 + y) + 3y = 180

50 + 2y + 3y = 180

5y = 180 - 50

5y = 130

y = 26

Substitute y = 26 into eqn. 1:

x - 26 = 25

x = 25 + 26

x = 51

The solution is: (51, 26).

2. x - y = 19 -- eqn. 1

-2x + y/6 = 28 -- eqn. 2

Rewrite eqn. 1:

x - y = 19

x = 19 + y

Substitute x = 19 + y into eqn. 2:

-2(19 + y) + y/6 = 28

-38 - 2y + y/6 = 28

-11y/6 = 28 + 38

-11y/6 = 66

-11y/6 (-6/11)= 66(-6/11)

y = -36

Substitute y = 36 into eqn. 1:

x - y = 19

x - (-36) = 19

x + 36 = 19

x = 19 - 36

x = -17

The solution is: (-17, -36).

3. 2x - 3y = -5 -- eqn. 1

x + y/11 = 50 -- eqn. 2

x + y/11 = 50

x = 50 - y/11

Substitute x = 50 - y/11 into eqn. 1

2(50 - y/11) - 3y = -5

100 - 2y/11 - 3y = -5

-35y/11 = -5 - 100

-35y/11 = -105

-35y/11(-11/35) = -105(-11/35) (multiplication property)

y = 33

Substitute y = 33 into eqn. 2:

x + 33/11 = 50

x + 3 = 50

x + 3 - 3 = 50 - 3

x = 47

The solution is (47, 33).

4. Solving the last one, we will definitely have the solution, (-31, -56).

The transformation is a reflection across the y-axis (the line x = 0).

On the image we can see two triangles, both are at the same distance of the vertical axis.

We also can notice that the figure is reflected, this is, the longest point of the triangle points to opposite ways.

With this we can conclude that we had some kind of reflection. Particularly, because both triangles are a the same distance of the vertical axis, we can conclude that the reflection was across the line x = 0.

a) The interest if computed using simple interest for 3 years at 2% is $120.

c) The interest when compounded continuously for 3 years at 2% is $123.67.

d) The difference in total interest between using simple interest and continuously compounding is $3.67.

Simple interest is a straightforward way of computing the interest paid on a loan.

The formula for calculating simple interest is P x R x T, where P = Principal, R = Rate, and T = Time.

The formula for continuous compounding first computes the future value (FV) from which the present value (PV) is deducted, as follows:

FV = PV x e ^ (i x t), where e is the mathematical constant approximated as 2.7183.

Principal = $2,000

Rate of interest = 2%

Period = 3 years

Simple Interest = $120 ($2,000 x 2% x 3)

Continuous compounding = FV - PV

FV = $2,000 x 2.7183 ^ (0.02 x 3)

= $2,000 x 1.06183697

= $2,123.67

Interest = $123.67 ($2,123.67 - $2,000)

The difference in total interest = $3.67 ($123.67 - $120)

Thus, continuous compounding produces a difference in the interest of $3.67 when compared to simple interest.

Based on the fact that the rectangular plot has a length that is 10 m longer than the width, the equation that will help to find area of the rectangular plot of land is 10x + x² = 10,000

To find the area of the plot of land is the same as finding the area of a rectangle which is:

Area of a rectangle = Length x Width

Assuming the width of the rectangular plot of ground is x, then the length would be:

= 10m + x

= 10 + x

The area of the rectangular plot of ground can therefore be found by the formula:

Area of a rectangle = Length x Width

10,000 square meters = (10 + x) × x

10,000 square meters = 10x + x²

10x + x² = 10,000

In conclusion, an equation that can help you to find the dimensions of the plot of ground is 10x + x² = 10,000.

The option that is an equivalent expression of 15x² +12x + 8 is C. 12x + 15x² + 8.

Expressions that are equivalent do the same thing even when they have distinct appearances. When we enter the same values for the variable, two algebraic expressions that are equivalent have the same values.

If two systems of equations have the same solution, they are equivalents. In algebra, 2(2x - 3y + 6) is equal to 4x -6y + 12 as an example of an equivalent expression.

In this case, it should be noted that 15x² +12x + 8 is the same as 12x + 15x² + 8. Therefore, the correct option is C.

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

Answer:

Equation of line is given as y = mx + c, where m is the gradient and c is the y-intercept.

First find the gradient.

Formula of gradient is given as (y2-y1)÷(x2-x1) or (y1-y2)÷(x1-x2)

Gradient = (-1-(-2))÷(3-(-2))

= (-1+2)÷(3+2)

= 1/5

Equation is y = 1/5 + c

Substitute either one of the points into the equation to find c.

-2 = 1/5(-2) + c

c = -8/5

Hence equation of the line is y = 1/5x - 8/5

Step-by-step explanation:

So whenever sometimes says "how many is x larger than y", it just means what is x divided by y. For example 4 is 2 times as much as 2 because 4/2 = 2

With this being said we can simply divide two numbers

[tex]\frac{2*10^{12}}{5*10^6}[/tex]

Whenever you divide scientific notation you simply divide the two coefficients and subtract the exponents from the base 10

So: [tex]\frac{2*10^{12}}{5*10^6} =\frac{2}{5} * 10^{12-6}[/tex]

This gives you a result of: [tex]0.4 * 10^6[/tex]

Since we want the coefficient to be: [tex]1\le c < 10[/tex] we can take one of the 10s from the base, since 10^6 is just 6 tens being multiplied by each other and we can "borrow" one of them to get: [tex]0.4*10^6=0.4*10*10^5[/tex] which simplifies to: [tex]4*10^5[/tex]

Answer: The angles in an equilateral triangle are always 60°. When a triangle has two congruent sides it is called an isosceles triangle. The angles opposite to the two sides of the same length are congruent. A triangle without any congruent sides or angles is called a scalene triangle.

If a tire on the snowplow with a diameter of 3.2 ft turns 47 times then, the length of the street is 472.3 feet.

To clear a street the city workers use a snowplow. The diameter of the tire of the snowplow is 3.2 ft.

The tire has to turn 47 times to cover the total length of the street.

Now, we know that the circumference of a circle is given as:

C = 2πr where r is the radius of the circle. And the radius of a circle is half of its diameter.

Therefore, the circumference of the circle can be written as:

C = πD where D is the diameter of the circle.

Now, to calculate the total length of the street we will find the product of the circumference and the number of times the tire has to turn to cover the street.

Therefore,

Length of the street, L = nC

L = nπD

L = 47 × 3.14 × 3.2 ft

L = 472.256 ft

L = 472.3 ft

Hence, the length of the street is 472.3 feet.
