First, you need to set the equation equal to zero:
n^2 + 7n + 10 = 0
Now we factor. We need to find two numbers that add up to 7 and multiply to 10.
2 + 5 = 7
2 * 5 = 10
Now, we just need to write this as a polynomial:
(n + 2) (n + 5)
is our answer.
Hope this helps!
Answer: 4
Step-by-step explanation:
x - 2y =10
x = 10 + 2y
... cancel like terms (y + 5)
= 4
The answer is 28.09 g. I hope this helped.
L:w=5:7
l/w=5/7
cross multiply
7l=5w
(7/5)l=w
P=2(L+W)
P=72
72=2(L+W)
divide both sides by 2
36=L+W
W=(7/5)L
36=L+7/5L
36=12/5L
times both sides by 5
180=12L
divide both sides by 12
15=L
W=(7/5)L
W=(7/5)15
W=21
length=15ft
width=21ft
dimeitions are 15 by 21ft
Answer:
A. 2⁵ is the answer.
D. 3³ - 3² too.
Step-by-step explanation:
2⁵ = 32
3³ - 3² = 27 - 9 = 18
