Answer:

Step-by-step explanation:

A square has 4 sides of equal length.

The perimeter of the square is the sum of the lengths of the sides of the square.

P = perimeter; a = length of 1 side

P = a + a + a + a

P = 4a

We are told the perimeter is 72 yd.

4a = 72 yd

Divide both sides by 4.

a = 72/4 yd

a = 18 yd

Answer: 18

Need help breaking this down step by step Distribute and combine 1/2(n-8)+7-n

PIT_PIT [208]

Answer:

$3-\frac{1}{2}n$

Step-by-step explanation:

We will use the distributive property shown below to break it down first.

Distributive Property: $a(b-c)=ab-ac$

The expression is:

$\frac{1}{2}(n-8)+7-n$

Let's distribute:

$\frac{1}{2}(n-8)+7-n\\=\frac{1}{2}(n)-\frac{1}{2}(8)+7-n$

Now, we multiply:

$\frac{1}{2}(n)-\frac{1}{2}(8)+7-n\\=\frac{1}{2}n-4+7-n$

Now we combine like terms (variables and numbers separately):

$\frac{1}{2}n-4+7-n\\=-4+7-n+\frac{1}{2}n\\=3-\frac{1}{2}n$

This is the simplified expression.

The function y = f(x) is graphed below. What is the average rate of change of the

stepladder [879]

Answer:

Average rate of change = 1

Step-by-step explanation:

Average rate of change of a function between x = a and x = b is defined by,

Average rate of change = $\frac{f(b)-f(a)}{b-a}$

We have to find the average rate of change of the function in the interval 2 ≤ x ≤ 4

Therefore, average rate of change of the function = $\frac{f(4) - f(2)}{4-2}$

From the graph attached,

f(4) = 4

f(2) = 2

Average rate of change = $\frac{4-2}{4-2}$

= 1

Therefore, average rate of change of the function in the given interval is 1.
