Answer:
16 - 21x
step-by-step explanation:
15 x 3 - 5x^2 + 6x - 2
add like terms
15 + 3 - 2
-5^2
-25 + 6
- 21
16 - 21x
Answer:
x² + 6x + 5 = 0
Step-by-step explanation:
Given
x² + 6x + 8 = 3 ( subtract 3 from both sides )
x² + 6x + 5 = 0 ← in standard form
Answer:
Step-by-step explanation:
For the first few exponents multiply and the rest they add because like terms.
The trick is that when you raise a power to a power you multiply. Otherwise you add if the base value is the same.
Given:
Our first step would be to distribute the (6-2v) by -1, since there is an understood -1 in front of the parenthesis. We are then left with:
Combine like terms.
Add 6 to both sides to isolate 9v on one side of the equation.
Divide both sides by 9 to isolate v.
Simplify.
I think it is B
