Answer:
Width = w
Length = 4w + 6
Area = 130 in2
Area = W X L = 130
So, w X (4w + 6) = 130
4w2 + 6w = 130 by distributing
-130 -130
4w2 + 6w - 130 = 0
Step-by-step explanation:
Answer:
25%
Step-by-step explanation:
First you have the fraction of 3/12 and need to turn it into a decimal. So to do that you divide 3 by 12 = 0.25. So your percent is 25%
Answer:
45.6°
Step-by-step explanation:
take the inverse cosine of 7/10:
you get about 45.573°
they want to the nearest 10th, so it would be 45.6°
-3(s-1) + 5s
we are going to distribute the -3 through the parenthesis...all that means is multiply -3 by everything in the parenthesis.
-3 * s + (-3)* -1 + 5s
-3s + 3 + 5s...now we combine like terms
-3s + 5s + 3 =
2s + 3
