Answer:
1) 2a+4a+10-6= 6a + 4
2) 3x-5x+7-7= -2x
3) - 15b+10 +10b= -5b + 10
4) - 4d+d-8-6+3b= - 3d - 14 +3b
Answer:
I am 99.99% sure its D.
Step-by-step explanation:
That red line is on the negative side of the x-axis and since all the numbers are 7 I'm just gonna assume that its a negative 7. Good luck sugar plum ;)

Answer:
Option D (8,4)
Step-by-step explanation:
we know that
The dilation centered at the origin (0,0) is very simple. To find out the image point multiply the scale factor to the x and y-coordinates of the pre-image point.
so
(2*4,2*2) -----> (8,4)
First, find the area for the kitchen floor: 16.5*15=247.5 squared feet
Then find the area for one tile: 0.5*0.5=0.25 squared feet
Finally, divide the mayor area between the minor: 247.5/0.25= 990 tiles.
Also you can do it in this another way:
First, divide length of the kitchen floor between the length of one tile: 16.5/0.5=33
Then, do the same for the height: 15/0.5=30
Finally multyply both results: 33*30= 990 tiles.
