Answer:
solving a quadratic equation by factoring
using the quadratic formula
Step-by-step explanation:
Answer:
The answer is -x+26.
Step-by-step explanation:
First you distribute the -3 into the parthensis and you get -3x+15. You write the whole expression again plus the -3x+15 you got from the distributing part so 8-3x+15+2x+3. You combine the like terms so the x with the x and the numbers with the numbers. From there you get the answer of -x+26. I hope this helps you!

Answer:
x = 32, ∠A = 132
Step-by-step explanation:
A and B are equal. Set both equations equal to each other.
5x - 18 = 3x + 42
Add 18 to both sides and subtract 3x from both sides.
2x = 60
Divide both sides by 2.
x = 30
Now plug x back in to solve for angle A.
5(30) - 18 = 132
If you would like to know the factored form of x^6 - 9, you can do this using the following steps:
x^6 - 9 = (x^3 + 3) * (x^3 - 3) = x^3 * x^3 - 3x^3 + 3x^3 - 3 * 3 = x^6 - 9
The correct result would be (x^3 + 3) * (x^3 - 3).
