The area of a square is the squared side, it means
[tex]A=l^2[/tex]It means, for A, which has a side of 5, the area is
[tex]5^2[/tex]For B, which side is 12, its area is
[tex]12^2[/tex]For C, the area is
[tex]13^2[/tex]Andre has to paint (solve each power):

The area of the triangle below is 24.75 square centimeters. What is the length of the base?
Answers
Okay, here we have this:
Considering the provided figure and information, we are going to calculate the requested measure, so we obtain the following:
So to calculate the length of the base, we will solve in the formula for the area of the triangle, we have:
Triangle Area=(Base*height)/2
Triangle Area*2=Base*height
Base=(Triangle Area*2)/height
Let's replace:
[tex]\begin{gathered} Base=(24.75cm^2\cdot2)\frac{\placeholder{⬚}}{5.5cm} \\ =\frac{49.5cm^2}{5.5cm} \\ =9cm \end{gathered}[/tex]Finally we obtain that the length of the base of triangle is 9 cm.

Identify the factors of the expression x^3 +4x^2-16x-64.
Answers
Solution:
Consider the following polynomial:
[tex]x^3+4x^2-16x-64[/tex]By grouping terms, we get that the above polynomial is equivalent to the following expression:
[tex](x^3+4x^2)+(-16x-64)[/tex]Now, we can apply common factor:
[tex]x^2(x^{}+4^{})-16(x+4)[/tex]again, applying a common factor, we get:
[tex](x^2-16)(x+4)[/tex]Note that the left factor is a difference of squares, therefore, the above expression is equivalent to:
[tex](x-4)(x+4)(x+4)[/tex]this is equivalent to:
[tex](x-4)(x+4)^2[/tex]So that, we can conclude that the factors of the given expression are:
[tex](x-4)[/tex]and

Answers
You have the following information:
- Two-thirds (which means 2/3) of the people on a hike are adults.
- There are 36 adults
In order to calculate the number of people, you consider that 36 is 2/3 of the total people. If you name x as the total people, the number of adults is 2/3x. Thus, you can write the following algebriac expression:
2/3 x = 36
you solve the previoues equation for x. First, you multiply both sides by 3 and you divide both sides by 2.
x = 36(3/2) = 108/2 = 54
Hence, the number of people on the hike is 54

The slope-intercept form of the given equation is y = 8x - 9
What is slope intercept form?
Using a straight line's slope and the location of its y-axis intersection, the slope-intercept equation can be used to determine the general equation of the line. Y = mx + b is the equation in slope-intercept form.
The slope-intercept form is y=mx+b, where
m is the slope and
b is the y-intercept.
Here, we have
Given equation = -8x + y = -9
Rewrite in slope-intercept form.
Add 8x on both sides of the equation and we get
y = -9 + 8x
y = 8x - 9
Hence, the slope-intercept form of the given equation is y = 8x - 9

To solve for x in any specific equation, we need to isolate x in one side of the equation. we can do that by adding, subtracting, multiplying, or dividing by a specific number on both sides of the equation.
For example:
X + 3 = 7
X + 3 - 3 = 7 - 3
X = 4
We solve for x when we subtract 3 on both sides of the equation.

The principle behind the Exterior Angle Theorem is that:

In this question, we have that :
X + ( X - 48 ) = X + 50

2X - X = 50 + 48
X = 98 Degrees.
CONCLUSION: The value of X = 98 Degrees.
Jessica was just offered a position as the Head Makeup Consultant. As a manager she will not earncommission or overtime.

Will Jessica earn more as an hourly paid employee or manager?How much more or less? Show work for credit.
Answers
Assuming there are 52 woking weeks in a year (Since it is the standard used by companies). And in week Jessica can have a maximum of 40 hours, we can conclude that;
[tex]\begin{gathered} \text{Hourly rate (H) =}\frac{38,500\text{ per year}}{52\text{ we}eks\text{ per year (40 hours per we}ek\text{)}} \\ \text{Hourly rate (H) = }\frac{38,500}{52(40)} \\ H\text{ = 18.51} \end{gathered}[/tex]Therefore Jessica's hourly rate is $18.51.
And by calculating her salary per year if she is paid hourly, let us again assume that there are 52 working weeks in a year and she works 8 hours per day 5 times a week as the standard working hours. We get;
[tex]\begin{gathered} \text{Yearly Salary (paid by hour) = 18.51/hour x 52 w}eeks\text{ x 8 hours/day x 5 days/w}eek \\ \text{Yearly Salary (paid by hour) = 18.51 x 52 x 8 x 5} \\ \text{Yearly Salar (paid by hour) = 38,500.80} \end{gathered}[/tex]Therefore Jessica's salary per year if she is paid hourly is $38,500.80, so there is a $0.80 difference between her initial salary.

Distributive Property
The distributive property of the product with respect to the sum states that if a product and a sum are to be operated like follows:
x* ( y + z )
Then the result is the product of x by each term separately:
x* ( y + z ) = x*y + x*z
Now, we have the expression:
8 ( 2m + 1 )
Applying the distributive property:
8 * 2m + 8 * 1
