Answer:
Step-by-step explanation:
If the books length (L) is three times as long as the width (W), the equation for area is this:
L · W = 20 inches,
3W · W = 20 inches - substituting L for 3W
So then the books perimeter is

Answer:
A). slope = -1/12 y-intercept = 3/2
Step-by-step explanation:
y = -1/12x + b
2 = -1/12(-6) + b
2 = 1/2 + b
3/2 = b
y = -1/12x + 3/2
Answer:
14
Step-by-step explanation:
You add 50 and 26 together to get 76, then you subtract 90 and 76 to get 14
In that statement of a function, 'a', 'b', and 'c' all represent
plain old ordinary constant numbers.
