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

two? xd

step-by-step explanation:

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb
