I’m pretty sure it’s x=80? it seems like x+30 has to equal 110 and 80+30=110.
Step-by-step explanation:
if x-4 is a factor of 2x^3 + x^2- 26x - 40
then f(4) = 0
f(x) = 2x^3 + x^2- 26x - 40
f(4) = 2(4)^3 + (4)^2 - 26(4) - 40
f(4)= 2(64) + 16 - 104 - 40
f(4) = 128 + 16 - 104 - 40
f(4) = 0
hence factorize completely is the photo

<em>What is the number sentence for "1 less than n is the sum of z and 2?"</em>
<em> </em>
<em> </em>
❖ First, Notice it says "1 less than n". This expression indicates that
we subtract 1 from n, which looks as follows:-

❖ Now, It also says "the sum of z and 2". This indicates that we add z and
2:-

❖ Now, Combine these two little expressions into one equation:-
