I got that question and the answer C
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:
(6 , 14)
Step-by-step explanation:
We are given the expression y = 8 + x and are asked to find which of the following order pairs will be the solution for the expression.
This involves substitution, the first number within the ordered pair represents x, while the second represents y, all you need to is plug in both numbers to see if it comes out as true.
(4,13)
13 ≠ 8 + 4
(2,16)
16 ≠ 8 + 2
(11,3)
3 ≠ 8 + 11
(6,14)
14 = 8 + 6
Considering when plugging, D is the only equation that makes sense, therefore it is the answer and solution.
Tracy should deposit 1,369.86 to earn 3,000 in 5 years at 4% interest rate compounded 4 times a year
Given:
Compounded Interest = 3000
Term = 5 year
Frequency = 4 times a year
interest rate = 4%
Principal = unknown.
C.I = Principal × (1 + rate)^t
3000 = Principal × (1.04⁴)⁵
3000 = Principal × 1.17⁵
3000 = Principal x 2.19
3000/2.19 = Principal
<span>1,369.86 = Principal</span>
