-3(x + 5) = -9
-3x + -15 = -9
-3x - 15 = -9
-3x - 15 + 15 = -9 + 15 (we added 15 to both sides of the equation because now, the 15 on the left side cancels out).
-3x = 6
-3x/-3 = 6/-3
X = -2
So, in conclusion, X is equal to -2.
A is 6 because so is the side across from it
And B is 8 because it the same size just flip it

(t^2+1)^100
USE CHAIN RULE
Outside first (using power rule)
100*(t^2+1)^99 * derivative of the inside
100(t^2+1)^99 * d(t^2+1)
100(t^2+1)^99 * 2t
200t(t^2+1)^99
The answer would be option D.
10a^3 + 91a^2 + 54a - 792
Answer:
42 degrees
Step-by-step explanation:
To find the complement of an angle, subtract that angle from 90.
90 - 48 = 42
