The perimeter of a rectangle is 15x + 17 y if the length is 7/2x + 7y then find the width of the rectangle
a) 4x + 3/2y

b) 8x + 3y

c) 8x + 10y

d) 4x + 3y

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.

Which letters from the table represent like terms? a and b b and c a and d b and d
