What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The prime factorization of the expression can be done as,
9 + (2×24)
= (3×3) + (2×2×2×2×3)
= 3 [3+(2×2×2×2)]
= 3 [3 + 16]
= 3 (19)
= 57
Hence, the simplification of the given expression 9 + (2×24) is 57.

f(x) = x² + 2x − 3
Find f (2)
f(2) is equal to type your answer...
Answer:
f(2) = 5
Step-by-step explanation:
Given: f(x) = x² + 2x - 3
We are asked to find the value of the function when x = 2.
In the function, substitute 2 as the value of x and simplify:
f(2) = (2)² + 2(2) - 3
f(2) = 4 + 4 - 3
f(2) = 8 - 3
f(2) = 5
When x is equal to 2, the value of the function is 5.

A shirt on sale for 25%off. Sandy paid 7.50 for the shirt. What was the shirts regular price
£10
Step-by-step explanation:
firstly what you have to do is
since the percentage is decreased
we will say 100 - 25% = 75%
then we say 7.50/75% = 10
So we know that the original price was
£10 pounds
As 10- 25%= 7.5
The shirt's regular price is 10.
Given,
A shirt on sale for 25%off.
Sandy paid 7.50 for the shirt.
We need to find the regular price.
The regular price is the same as the selling price.
We have,
Regular price = Paid price + offer discount%
offer discount = 25%
Paid price = 7.50
If after 25% off Sandy paid 7.50 which means Sandy paid only 75% of the price.
The regular price is always 100%
= Paid price + offer discount%
= 75% + 25%
So we have,
75% = 7.5
Multiplying 25/75 on both sides.
25/75 x 75% = 7.5 x 25/75
25% = 2.5
We see that the offer discount is 2.5.
We have,
Regular price = Paid price + offer discount%
= 7.50 + 2.5
= 10
Thus the shirt's regular price is 10.

Alex believes the honor roll students at his school have an unfair
advantage in being
assigned to the science class they request. He asked 500 students at his school the
following questions: Are you on the honor roll?" and "Did you get the science class you
requested?" The results are shown in the table below:

Did not get science class requested 80

500
Help Alex determine if all students at his school have an equal opportunity to get into
the science class they requested. Show your work, and explain your process for
determining the fairness of the class assignment process.
According to the information provided, it can be inferred that the conclusion reached by Alex is that there are no advantages to honor roll students.
How to calculate the percentage of students who received the requested classes?To calculate the percentages of students who received the requested classes, we must take into account the data in the table. Additionally, we must perform the following operations:
144 ÷ 100 = 1.44
64 ÷ 1.44 = 44.44%
According to the above, the percentage of students who are on the honor roll and receive their classes is 44.44%.
To calculate the percentage of students who are not on the honor roll and receive their classes, we do the following operation.
356 ÷ 100 = 3.56
315 ÷ 3.56 = 88.48%
According to the above, it can be inferred that the students who are on the honor roll do not have advantages over the others because the percentage of students who are not on the honor roll and receive their science classes is greater than the percentage of students who are on the honor roll and receive their classes.

What is the image point of (1, -2) after a translation right 4 units and down 4 units?
Answer:
Hello!!!!
THE ANSWER: (5, -6)
Please read the explanation... it always helps... trust me...
Step-by-step explanation:
Okkeeeee lets beginnnn....
A translation is when you move a point of shape in a coordinate plane
so a translation of a point to the right means you are moving the point to the right of the coordinate plane meaning the positive side of the x-axis... so in this case you will need to add 4 to the x-coordinate....
simarily to the "down four units"
moving it down means subtraction.... meaning you need to subtract 4 from -2 which gets you -6...

Consider the line y=-2/3x+9 . Find the equation of the line that is parallel to this line and passes through the point (-8,3) . Find the equation of the line that is perpendicular to this line and passes through the point (-8,3) .
The equation of line which is parallel to line is y = (-2x-7)/3.
What is Gradient?
Gradient is the ratio between change in y-axis to change in x-axis.
Here, Given Equation of line is y = [tex]\frac{-2}{3}x+9[/tex]
gradient of line m₁ = -2/3
Equation of line passing through point (-8, 3) and gradient -2/3 (parallel to given line) is
(y - y₁) = m₂(x - x₁)
( y - 3) = -2/3(x+8)
3y - 9 = -2x -16
3y = -2x -16 + 9
3y = -2x -7
y = (-2x-7)/3

Stephanie is helping a midwife weigh new-born babies. The scales are in pounds but the sheet she has to complete is in kilogrammes. The baby weighs 8.06 lbs. When she converts this on a calculator the display reads 3.65595152. What is this in kilogrammes to 3 decimal places?
The weight of baby in kg is, 3.659 kg.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The baby weighs 8.06 lbs.
Now, We know that;
⇒ 1 pound = 0.454 kg
Hence, The weight of baby in kg is,
⇒ 8.06 pounds = 8.06 × 0.454 kg
= 3.659 kg

Based on the SAS congruence criterion, the statement that best describes Angie's statement is:
Two triangles having two pairs of congruent sides and a pair of congruent angles do not necessarily meet the SAS congruence criterion, therefore Angie is incorrect.
What is congruency?The Side-Angle-Side Congruence Theorem (SAS) defines two triangles to be congruent to each other if the included angle and two sides of one is congruent to the included angle and corresponding two sides of the other triangle.
An included angle is found between two sides that are under consideration.
See image attached below that demonstrates two triangles that are congruent by the SAS Congruence Theorem.
Thus, two triangles having two pairs of corresponding sides and one pair of corresponding angles that are congruent to each other is not enough justification for proving that the two triangles are congruent based on the SAS Congruence Theorem.
The one pair of corresponding angles that are congruent MUST be "INCLUDED ANGLES".

For immediately line graphs there is a linear relationship between the x and y values and so the line is instantly and should be drawn with a ruler. The gradient determines how steep the road is and the y-intercept tells us the vicinity wherein the immediate line intersects the y-axis.
Why is a graph a direct line?It continually goes up in steps of equal length, so it is a straight line. that is first-class as a way because it goes. It identifies the defining assets of a linear feature—that it has a constant rate of exchange—and relates that property to a geometric feature of the graph.

the sum of all angles in a triangle is always 180°.
so, when T is 40°, that leaves 180-40 = 140° to the other 2 angles. in an isoceles triangle they must be equal to each other, so they are half of the remaining 140°, which is 70°.
