Answer:
Part 1) The perimeter is
Part 2) The area is
Step-by-step explanation:
Part 1) Find the perimeter
we know that
The perimeter is equal to the circumference of the exterior circle plus the circumference of the interior circle
so
Part 2) Find the area
we know that
The area of the figure is equal to the area of the larger circle minus the area of the smaller circle
so
The expression is:
The value of expression when x=5 is 3
Further explanation:
We have to translate the given sentence to form an expression.
Given
"The sum of a number x and 4"
This will be equal to:
"all divided by 3"
We will put x=5,
The expression is:

5 cents is the answer because u can use 7 5 cent pieces or a 25 cent peice and 10 cent piece to get 35. 7-2=5
ANSWER: width (w) = 11 ft
w = 3L + 5
P = 2w + 2L = 26
P = 2(3L + 5) + 2L = 26
P = 6L + 10 + 2L = 26
P = 8L + 10 = 26
Now solve for L
8L = 16
L = 2
Now plug in 2 for L in the W equation
w = 3L + 5
w = 3(2) + 5
w = 6 + 5
w = 11
Width is 11 ft
Length is 2 ft
LAND is equal to 91 because it has 9 straight lines and one curved one.
