Which expression is equivalent to 9x – (x – 8)(x + 1) + 10x? -x^2 + 19x + 8
-x^2 + 26x + 8
8x^2 +10x + 8
8x^2 +26x + 8

-x^2 + 26x + 8

Step-by-step explanation:

9 x - (x - 8) (x + 1) + 10 x is always equal to -x^2 + 26 x + 8

option 2

Step-by-step explanation:

9x – (x – 8)(x + 1) + 10x

9x – (x² + x — 8x — 8) + 10x

9x – (x² — 7x — 8) + 10x

9x – x² + 7x + 8 + 10x

-x² + 26x + 8

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
