Answer:
-6a-48
Step-by-step explanation:
multiply each term in the parenthesis by -6
-6 * a -6 * 8
8 = x% * 400
8 = x/100 * 400
8 = x * 4
4x = 8
Divide 4 on both sides.
x = 8/4
x = 2
2 percent<span> of 400 is 8.</span>
Answer:
7(b^2 -2)(b^2 +2)
Step-by-step explanation:
Factoring the common factor 7 from both terms, you get the difference of squares. That can also be factored.
v = 7(b^4 -4) = 7(b^2 -2)(b^2 +2)
The difference b^2-2 will have irrational factors, so does not meet the problem requirements. This is the factorization over integers.
