You are basically just adding, so combine like terms.
3x^2 + 5x^2 = 8x^2
6x - 2x = 4x
4 - 8 = -4
So the answer is D.
Answer:
x = -2
Step-by-step explanation:
10x+8=3x-6
subtract 10x-3x
7x+8= -6
subtract -6-8
7x=-14
divide 7 into -14
x = -2

5(100)= 500
5(90)= 450
5(8)= 40
500+450+40= 990
The answer is 990. Hope this helps!
