Answer:
< A = 148°
Step-by-step explanation:
<A = <B → 6x - 2° = 4x + 48° → 2x = 50° → x = 25°
<A = 6(25°) - 2° = 150° - 2° = 148°
Answer is C. 
First start by subtracting the exponents from top to bottom
let's start with a so a^2 - a^-2 2 - (-2) = 4
Now B: b^-3 - b^2 so -3 - 2 = -5
This leaves you with a^4 b^-5
However you cannot have a negative exponent so B must cross over and move to the bottom to become positive
Don't forget about the squared outside the parentheses. Both exponents must be multiplied by two to get 8 and 10
Answer: Lets divide by 8. My god, those coefficients are large.
x^3 - 8x^2 + 20x - 16 = 0
Possible integral roots are: +1, -1, +2, -2, +4, -4, +8, -8
If x = 2, f(x) = 8 - 32 + 40 - 16 = 0
Hence, x-2 is a factor.
Use synthetic division to get: x^2 - 6x + 8 = (x-4)(x-2).
Therefore, there are two integral roots: +2 and +4.
