Answer:
4x +3/2y
Step-by-step explanation:
The perimeter is twice the sum of length and width. We can use this to find the width.
P = 2(L+W)
15x +17y = 2(7/2x +7y +W)
15x +17y = 7x +14y +2W . . . . . . eliminate parentheses
8x +3y = 2W . . . . . . . . . . . . . . . subtract 7x +14y
W = 4x +3/2y . . . . . . . divide by 2
The width of the rectangle is 4x +3/2y.
Answer:
3x-y-7 - 6x-y-10 would leave you with -3x-3
Step-by-step explanation:
When subtracting 6x-y-10 from 3x-y-7, 3x - 6x would leave you with -3x. -y and -y would cancel out. lastly, -7 - (-10) is equal to -3. When putting all of this together, you are left with -3x-3.
