Answer: H. -2
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given points are 
And given transformation is 
We will start from left to right.
First transformation is reflection about x-axis.
When we reflect about x-axis 
So, ![(-1,-8)=[-1,-(-8)]=(-1,8)](https://tex.z-dn.net/?f=%28-1%2C-8%29%3D%5B-1%2C-%28-8%29%5D%3D%28-1%2C8%29)
Now next transformation is dilation with a factor 4.
If we do dilation with a factor 
to the point 
New co-ordinates after dilation became 
So, 
It is known to us that the Eqyptian pyramids have a square-shaped base and four sides which are equilateral triangles. The angles formed between the edge of the base and the equilateral side is 90°, thus, we can clearly apply the pythagorean theorem.

You need to cross multiply.
(t+7)(t+7)=t^2+7t+7t+49. t^2+14t+49
9*25=225
t^2+14t+49=225
Subtract 225 from both sides
t^2+14t- 176=0
(t-8)(t+22) =0
8 and -22
