Answer:
D is incorrect this is your answer
Answer:
x^2 +x+2
Step-by-step explanation:
f(x) = x^2+3
g(x) = x-1
f(x)+ g(x) = (f+g) (x)
x^2+3+ x-1
x^2 +x+2
I'm guessing here, but I may be right. The answer is x=0
If I'm wrong please correct me!!
Well first lets do the distributive property so the left side is already done 28, now the right side -4 (2x+7) when you do that you get -8x-28. So now we have 28=-8x-28. So now I would move the -28 to the left side and when you move stuff to the other side you change the sign so the sign will be positive 28+28 which is 56. Now you have 56=-8x. Now divide both side by -8 to have -7=x
Your Answer: x = -7
