Answer:
Hi, there your answer is
Question5: B.(x+3)(x-10)
Queston 6: D.(2x-2)(x+3)
Step-by-step explanation:
Answer:
Number of of tiles will be
.
Step-by-step explanation:
Given:
let 'x' represent the length of the room.
Width is 12 feet wider than its length.
Width = 
Area of tiles = 
We need to find number of tile along the inside of the room.
First we will find Area of room.
Area of room will be equal to length times width.
framing in equation form we get;
Area of room =
sq. ft.
Now Number of Tiles will be equal to Area of room divided by Area of tile.
framing in equation form we get;
Number of Tiles = 
Hence Number of of tiles will be
.
Answer:
Step-by-step explanation:
It doesn't look right to me, but you may not have the choices I would want to use. I think it should go
1/2
cos^2
sqrt(x)
+ 2)
The square root covers just the x, and nothing more.
Hi there!
6. x² + 6x = 27
subtract 27 on both sides to make the equation equal to 0.
x² + 6x - 27 = 0
(x - 3)(x + 9) = 0
x - 3 = 0 x + 9 = 0
x = 3 x = -9
7. k² - 13k + 36 = 0
(k - 9)(k - 4) = 0
k - 9 = 0 k - 4 = 0
k = 9 k = 4
8. g(x) is translated up 5 from f(x).
9. g(x) is reflected by x-axis, then translated 3 down from f(x).
Hope this helped! :)
Answer: 45
Step-by-step explanation:
By factor method,
3 = 1, 3
9= 3, 3
15= 3, 5
LCM= 3*3*5
