Answer:
12 feet
Step-by-step explanation:
w = width
w+2 = length
w(w+2) = 8
w² + 2w - 8 = 0
(w+4)(w-2) = 0
w = -4 <em>exclude because a length cannot be negative</em>
w = 2
length = 2+2 or 4
P = 2(2)+2(4)
P = 4+8 or 12
16/40 simplify by GCF divide both by 8 2/5 Answer choice C hope i could help
The answer is less than <
Answer:
20 cm
Step-by-step explanation:
We can use ratios to solve
We know x = 7 since they are of equal length
x x+7
----- = -------
10 y
7 7+7
----- = -------
10 y
Using cross products
7y = 14*10
7y = 140
Divide by 7
7y/7 = 140/7
y = 20
