Answer:
1 - 3 (1 quarter is 25 and a dime is 10, so, 3.)
4 - 10
6 - 15
14 - 33
Step-by-step explanation:
First, find the area of the circle using the formula A=pi r^2.
A=pi (2x+3)^2 = pi(4x^2 + 12x + 9)
Second, find the area of the rectangle inside by multiplying the polynomials.
(X+1)*(3x+2) = 3x^2 + 5x +2
Third, subtract the area of the rectangle from the area of the circle to find the area of the shaded region.
pi(4x^2 + 12x + 9) - 3x^2 + 5x +2 =area of shaded region
Or
(pi (2x+3)^2) - ((X+1)(3x+2)) = area of shaded region
Answer:
350 sq ft
Step-by-step explanation:
Given that:
840 sq ft area has a bedroom, kitchen and bathroom.
Let the area of bedroom be
sq ft.
Then the area of kitchen will also be
sq ft.
Let the area of bathroom be
sq ft.
As per question statement:

Tiles ordered to cover two kitchens and two bathrooms is 980 sq ft.
i.e.

Subtracting equation (1) from (2):
i.e. (2) - (1):
sq ft
Putting the value of
in (1):

Therefore, the carpet needed for each bedroom = <em>350 sq ft</em>
