Use absolute value to write an expression describing the size of each amount. an elevation of 250 feet.

The absolute value of a number is always positive.

if x > 0 , then = x

if x < 0 , then |-x| = x

Use the absolute value.

To find an expression for: An elevation of 250 feet.

Elevation mean the height of a place above the sea level.

An elevation of 250 feet =  +250

then, using absolute value:

Size of each amount,  

yes

step-by-step explanation:

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
