Answer:

The expression 3x+13 represents the side length of the square in units.

Step-by-step explanation:

Let the a be the side length of the square in units.

The perimeter of a square is

P=4a

It is given that a square has a perimeter of 12x+52 units. Substitute P=12x+52 in the above formula, to find the expression that represents the side length of the square in units.

12x+52=4a

Divide both sides by 4.

\frac{12x+52}{4}=\frac{4a}{4}

\frac{12x}{4}+\frac{52}{4}=a

3x+13=a

Therefore expression 3x+13 represents the side length of the square in units.

The graph of a function f is shown. Use the graph to estimate the average rate of change from x = –2 to x = 0
vodomira [7]

Answer:

Average rate of change = 2

Step-by-step explanation:

Formula to get the rate of change of a function between x = b and x = a is,

Rate of change = \frac{f(b)-f(a)}{b-a}

We have to calculate the average rate of change between x = -2 and x = 0

From the graph attached,

At x = -2,

f(-2) = 0

At x = 0,

f(0) = 4

Therefore, average rate of change = \frac{f(0)-f(-2)}{0-(-2)}

                                                          = \frac{4-0}{2}

                                                          = 2

Average rate of change of the given function between x = -2 and x = 0 is 2.
