Answer:A
Step-by-step explanation:
(x•2)/8+18=4
2x/8 +18=4
Collect like terms
2x/8=4-18
x/4=-14
Cross multiply
x=-14 x 4
x=-56
The fully factorized version of -x-5 is

What is Factorization?
Usually, factorization or factoring means writing a number (or another mathematical object) as a product of minor or more uncomplicated objects of the same kind.
Given -x-5 is a linear expression.
For factorizing, first, make the coefficient of x positive. For this take -1 common.
⇒ -x-5 = 
Now take the greatest common divisor (gcd) of absolute values of coefficients in x+5.
⇒ gcd(1,5) = 1.
Now take gcd 1 common in the expression.
⇒ 
⇒
.
∴ The fully factorized version of -x-5 is

Answer:
you have to add them together
n + n - 0.18n
We can rewrite it as
2n - 0.18n
And if we solve it
(2 - 0.18)n = 1.82n
So the equivalente expression is B.
I think it is 9 - x because 81-x^2/9-x = 9-x
