plugging x=-2 in the given equation we get

=12/3²
=12/9
=4/3
so answer is 4/3
Answer:
If you meant to simplify the expression,
-8b+4ab
if factor: 4b(a-2)
Step-by-step explanation:
To simplify an expression, combine the like terms.
8b+4ab-16b, 8b and -16b are like terms.
-8b+4ab, notice 4ab has an extra a before the b, so it is not a like term of -8b
To factor it out:
The expression -8b+4ab both includes b in it.
Thus,
b(-8+4a) -8 and 4 can be has GCF of 4
=4b(a-2).

Answer:
length = 13 inches
Step-by-step explanation:
let the length be x
hence, the width = x-9
perimeter = 2(x+x-9) = 34
2(2x-9) = 34
4x- 18 = 34
4x = 52
x = 13
