Find the perimeter of a rectangle with the lengths -3x + 4 and 2x + 7.

Question

kittymaniac · Answer

Assuming that (-3x + 4) and (2x + 7) are two legs of a rectangle, you can find the perimeter like this: P = 2 length + 2 width. 
 P = 2*(-3x + 4) + 2*(2x + 7) P = -6x + 8 + 4x + 14 P = -2x + 22 
 Hope this helps! :)

kittymaniac · Answer

The perimeter of the rectangle with sides − 3 x + 4 and 2 x + 7 is given by the formula P = − 2 x + 22 . This formula allows you to calculate the perimeter based on the value of x .
