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:
i dont know im sorry i wish you the best bro
Step-by-step explanation:
If there is more information then you should use it but if that is then yes it is possible if you think hard enough.
Increasing 50 by x% can be written as:
.................(1)
Decreasing 70 by x % can be represented by the expression:
...........(2)
Now we are given in the question that if we increase 50 by x% and 70 by x%, then the two values are equal.
so equating (1) and (2) , we get
bringing 0.01x to the left side:
taking 50 to the right side, subtracting it from 70
dividing both sides by 0.02
Answer x=2000
Answer:
Multiplication property of equality
Step-by-step explanation:
Given
Step 4: b = -27/8
Required
Which property justifies it?
First, it should be noted that step 4 is a result of step 3
When step 3 is multiplied by 3/8 on both sides, we have step 4;
i.e.
<em>The property that allows 3/8 be multiplied on both sides is referred to as the multiplication property of equality</em>
