Answer:
10
Step-by-step explanation:
The side to the right is 15. The side to the left is 5. You can subtract these two to find the length.
![y=2x^2+16\\y=2(x)^2+16](https://tex.z-dn.net/?f=y%3D2x%5E2%2B16%5C%5Cy%3D2%28x%29%5E2%2B16)
It is a positive-slope parabola with vertex of (0,16) "concave up"
Answer:
B = 2
Step-by-step explanation:
|b + 4| = 6
b + 4 = 6
b = 6 - 4
b = 2
So here is the solution of the given problem above.
To find the area we are just going to use this formula. A = L x W.
Let x be the width and 2x is the length. Given that the area is 8 square meters. So let us find x first.
Plug in the values:
8 = (2x)(x)
8 = 2x^2 << divide both sides by 2 and we get
4 = x^2
Then square 4 and x^ 2 and we got
2 = x
Therefore, the width of the room is 2 meters and the length 2x is 4 meters. Hope this is the answer that you are looking for.
Answer:
See below ~
Step-by-step explanation:
The given polynomial : <u>-2x + 1 + 2x²</u> needs to be written in the form :
- ax² + bx+c
- a is the coefficient of x²
- b is the coefficient of x
- c is the constant term
On rewriting in this asked format,
- 2x² - 2x + 1
- a = 2
- b = -2
- c = 1
