I need help on math:(

A. 10

Step-by-step explanation:

The perimeter is the sum of all the outside lengths

Therefore, to find the value of x, you must do:

x + x + 5 + x + 7 = 42

3x + 12 = 42

3x = 30

x =10

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
