Answer:

Step-by-step explanation:
has the form
known as a difference of squares. It factors into (a+b)(a-b). To find a and b you take the square root.


The factored for is (a+b)(a-b).
In this case, it is 
Answer:
x = 1.91 ft
Step-by-step explanation:
We use cosine because we are dealing with Adj and Hyp
cos 80 = x/11
x = 11 cos 80
x = 1.91 ft
Answer:
10 feet
Step-by-step explanation:
The formula for the Perimeter fo a rectangle
= P = 2L + 2W
Where:
L = Length
W = Width
From the question
P = 80 feet
W = 30 feet
Hence:
80 = 2L + 2(30)
80 - 2(30) = 2L
80 - 60 = 2L
20 = 2L
L = 20/2
L = 10 feet
Hence, the length of the fenced area = 10 feet
6 ÷ 1/3 = 6/1 x3/1 = 18 servings per box
Answer:
Pretty sure the width would be 70
Step-by-step explanation:
3920ft divided by 56 = 70
