Answer:
D. 6x-14
Step-by-step explanation:
So first we would do 3x^2+3x^2-5x^2
That would all cancel out so that would be 0.
Next we would do 3x-4x+7x, this would equal to 6x
Finally we would do -4-8-2, this would be equal to -14
Then the equation would be 6x-14
All you have to do is combine like terms.
Hope this helped!
The rectangle looks like
A —— B
D —— C
so AB = 84
BC = 63
AD = 63
CD = 84
