Triangle abc is being dilated with the center of dilation at the origin . The image of c point c’ had coordinates of (7.2,3.6) what is the scale factor of the dilation and what are the coordinates of point a

Let's follow the BEDMAS rule.

First we should do everything inside the brackets. According to BEDMAS we should do multiplication first before subtraction:

(28 × 5 - 5 × 190)

28 × 5 = 140
5 × 190 = 950

(140 - 950) = -810

So now we have:

(-810 - 2 × 5^-2) / 2^3

Next, we do exponents so:

5^-2 = 1/25
2^3 = 8

(-810 - 2 × 1/25) / 8

(-810 - 2/25) / 8

(-20252/25) / 8 = -5063/50

So now we have:

(-5063/50)^4 × 288

If we plug the first term into a calculator and out it to the party of 4, we get:

105136058.7

So that number times 288 we get:

3.03x10^10 as the answer
