If a function has roots -1 and -5, it must be in the form
![f(x)=a(x+1)(x+5)](https://tex.z-dn.net/?f=f%28x%29%3Da%28x%2B1%29%28x%2B5%29)
We can fix the coefficient a by imposing the passing through (0,-30):
![f(0)=-30=a(1)(5)\iff a=-6](https://tex.z-dn.net/?f=f%280%29%3D-30%3Da%281%29%285%29%5Ciff%20a%3D-6)
So, the function is
![f(x)=-6(x+1)(x+5)](https://tex.z-dn.net/?f=f%28x%29%3D-6%28x%2B1%29%28x%2B5%29)
A. After the mod. One wall is “x” longer than original (horizontal in diagram) and the other is “x” shorter (vertical)
(30+x)(30-x)
b. He original area = 30 x 30 = 900 sq. ft.
The mod. Area is (30+6)(30-6) = 36x24= 764 sq. ft.
So the room was largest to begin with when it was a square
Answer:
116
Step-by-step explanation:
Pemdas so do the 10 × 12 first... you get 120 the you go left to right so 3 + 120 = 123... subtract 7 from that and you get 116.
Triangle angles add to 180 degrees. Thus, x - 17, x - 22, and 3x + 19 add to 180.
Add like terms to get 5x - 20 = 180
5x = 200
x = 40
I believe it is false I am sorry if it’s not correct
