Okay, lets start with number 1.
is also equal to (x+3)(x+3)(x+3)
If you take the first two ones and multiple them out it ends up with or also know as
You see to multiply them you take the first number in the first group of parenthesis and use the distributive property on the second equation, then you do the same this but with the second number in the first equation.
So once you have you multiply it with your remaining (x + 3) using the distributive property to get
I hope this helps you get the answers for the other two.
Answer: 28 minutes
Step-by-step explanation:
If M1 men can do W1 work in working H1 hours per day and M2 men can do W2 work in working H2 hours per day (where all men work at the same rate), then
hence, It takes 28 minutes for 14 people to paint 14 walls.
The answer would be D
G(x) = (X-4)^2
