Answer:
30x - 18
Step-by-step explanation:
6(5x - 3)
<em>Distribute the 6 to both monomials.</em>
6 * 5x = 30x
6 * -3 = -18
<em>Combine both final monomials.</em>
30x - 18
1 - 7 + 7 + 3 + 3 = 20
2 - 3 + 3 + 4 + 3 = 13
3 - 7 + 7 + 2 + 2 = 18
4 - 2 + 2 + 9 + 9 = 22
5 - 3 + 1 + 3 + 1 = 8
20 + 13 + 18 + 22 + 8
33 + 18 + 22 + 8
33 + 18 + 30
63 + 18
= 81
Answer:
(x-8)(x^2-2)
Step-by-step explanation:
take x common from the first 2 terms and take -2 common from the last two terms. Then, take (x-8) common.
x^2(x-8)-2(x-8) = (x-8)(x^2-2)
Then they are supplementary angles which mean both of those angles add up to 180°
