6a² + 7ax - 3x²
6a² + 9ax - 2ax - 3x²
3a(2a) + 3a(3x) - x(2a) - x(3x)
3a(2a + 3x) - x(2a + 3x)
(3a - x)(2a + 3x)

![\huge\boxed{\sf Area\ of\ the\ circle = 1385.4\ in.\²}](https://tex.z-dn.net/?f=%5Chuge%5Cboxed%7B%5Csf%20Area%5C%20of%5C%20the%5C%20circle%20%3D%201385.4%5C%20in.%5C%C2%B2%7D)
Step-by-step explanation:
We have to find out the area of the square in order to find how many square inches were cut from the squared cloth.
Diameter = 42 in.
Radius = D / 2 = 42 / 2 = 21 in.
Area of circle = πr²
Where r = 21 in.
Area = (3.14)(21)²
Area = (3.14)(441)
Area of the circle = 1385.4 in.²

Answer:
<u>Width = 7 inches</u>
<u>Length = 23 inches</u>
Step-by-step explanation:
Let :
Equating to area :
- (2x + 9)(x) = 161
- 2x² + 9x = 161
- 2x² + 9x - 161 = 0
- 2x² - 14x + 23x - 161 = 0
- 2x(x - 7) + 23(x - 7) = 0
- x - 7 = 0
- x = 7
Dimensions are :
- <u>Width = 7 inches</u>
- Length = 2(7) + 9
- <u>Length = 23 inches</u>
Hello!
You put -1 in for x
F(-1) = (-1)^5 + (-1 + 3)^2
F(-1) = -1 + (2)^2
F(-1) = -1 + 4
F(-1) = 3
The answer is 3
Hope this helps!
