The larger right triangle with hypotenuse x + 5 and short leg x + 2 is similar to the smaller right triangle with hypotenuse x + 2 and short leg x.
Because of this similarity, we have
(x + 5)/(x + 2) = (x + 2)/x
Solve for x:
x(x + 5) = (x + 2)^2
x^2 + 5x = x^2 + 4x + 4
x = 4

Bob has 27 books.
Charles has two thirds as many books as Bob.
Charles has 18 books.
Jim has three times as many books as Charles.
Jim has 54 comic books.
Answer:
Step-by-step explanation:
In order to find the answer. You first have to find the measure of the whole circle, which is 180.
Then you subtract 180-95 to find y.
180-95=85
So y=85
Then you subtract 180 from 80
180-80=100
So x=100
z=80
So the answer is D.
L x w = 150+175t
=> l = (150+175t)/25
l = [25(6+7t)/25]
l = 6+7t
The expression of the length is l=6+7t
