Answer:
11x-9
Step-by-step explanation:
5+2(5x-7)+x=5+10x-14+x
= 11x-9
When you have an algebraic expression including brackets, you always multiply what's on the inside by what is on the outside. This means that you would do -2 × 5x = -10x, and then -2 × -6 = 12, so your answer would be -10x + 12.
I hope this helps!
Answer:
The first triangle is larger
Step-by-step explanation:
(1/2)(8)(10)=40
(1/2)(5)(13)=32.5
So you must be reflecting over the y=x line so your quadrates would be (4,-2) (5,-4) (3,-9)
