Answer:
-2w + 4
Step-by-step explanation:
Remove parenthesis because they make life semi-confusing but remember to distribute the negative: w^2 + 3w -w^2 - 5w + 4
Combine like terms: w^2 - w^2 cancel out ; 3w - 5w = -2w ; 4
-2w + 4

Answer:
5(9+x)
Step-by-step explanation:
5 x 9 = 45
then if do 5 times x it would look like 5x
So much stuff at once...
I'm only going to give you the information needed to do this.
All of these involve the 4 main exponent laws.
1) Multiplying.
When you multiply two 'numbers' that share the same base, you add exponents and keep the base the same. (ex. 4g²(4g⁴) = 4g²⁺⁴ = 4g⁶)
2) Dividing.
When you divide two 'numbers' that share the same base, you subtract exponents and keep the base the same. (ex. 3a⁷ / 3a⁴ = 3a⁷⁻³ = 3a³)
3) To the power of 1.
Anything to the power of 1 is the same. (ex. 5a¹ = 5a)
4) To the power of 0.
Anything to the power of 0 = 1. (ex. 2d⁰ = 2(1) = 2)
This should help.
Answer:
Step-by-step explanation:
w + g = 52
w = 4g - 3
(4g - 3) + g = 52
5g - 3 = 52
5g = 52 + 3
5g = 55
g = 55/5
g = 11....there are 11 green marbles
w + g = 52
w + 11 = 52
w = 52 - 11
w = 41 <=== there are 41 white marbles
