Answer:
Step-by-step explanation:
13p⁵ + 6p - 12p² -(-9p - p² - 13p⁵) = 13p⁵ + 6p - 12p² + 9p + p² + 13p⁵
{Distribute (-1) to the second expression}
= <u>13p⁵ + 13p⁵</u> <u>-12p² + p²</u> <u>+ 6p + 9p</u>
{Combine like terms}
= 26p⁵ - 11p² + 15p

Answer:
C
Step-by-step explanation:
As we can see, there are perfect squares in the first two expressions
thus, we have it that;
√(25x) = 5√x
√(4x) = 2√x
so we have the expression as;
5 √x - 2 √(x + 2 √x
= 5√x
Answer:
y = -24
Step-by-step explanation:
Direct variation is
y = kx where k is a constant
12 = k*(-1)
12/(-1) =k
-12 = k
The equation is y = -12x
Let x = 2
y = -12(2)
y = -24
