Multiply each term in the first set of parentheses by each term in the second set, then combine like terms.
7x x 3x^2 = 21x^3
7x x -4x = -28x^2
7x x 5 + 35x
-6 x 3x^2 = -18x ^2
-6 x -4x = 24x
-6 x 5 = -30
Combine like terms to get:
21x^3 - 46x^2 + 59x - 30
The answer would be c I hope it helps
Answer:
C
Step-by-step explanation:
Given that Q varies inversely as the square of p then the equation relating them is
Q =
← k is the constant of variation
To find k use the condition Q = 36 when p = 7
k = Qp² = 36 × 7² = 36 × 49 = 1764
Q =
← equation of variation
When p = 6, then
Q =
=
= 49 → C
Step 1: Replace f(x) with y: y=-8-5x
Step 2: Switch X and Y: X=-8-5y
Step 3:Solve for y: x+8=-5y ≈ y=(x+8)/-5
Step 4: Replace y with F^-1(x): f^-1(x)=(x+8)/-5 :)
X equals to eight probably
