Given:
L = W - 4
P = 2L + 2W
We can substitute 2L for 2(W - 4) = 2W - 8
So:
2W - 8 + 2W = P
P = 4W - 8
Answer is 4. 4W-8

Answer:
$4047
Step-by-step explanation:
For an interest rate r compounded n times per year for t years, the effective multiplier is ...
(1 +r/n)^(nt)
The multiplier for the first 5 years is ...
(1 +0.07/2)^(2·5) = 1.41059876
The multiplier for the last 5 years is ...
(1 +0.0728/4)^(4·5) = 1.43437218
Then the account value at the end of 10 years is ...
$2000(1.41059876)(1.43437218) ≈ $4047 . . . . balance after 10 years
Answer: the answer is W (-7, -2)

Answer:
Part A) The approximate perimeter of the concrete region is 
Par B) The exact area of the concrete region is 
Step-by-step explanation:
Part A) What is the approximate perimeter of the concrete region?
we know that
The perimeter of the composite figure is equal to
The radius of semicircle is
substitute
Part B) What is the exact area of the concrete region?
we know that
The area of the composite figure is equal to the area of semicircle plus the area of rectangle plus the area of triangle
so
The radius of semicircle is
