Dilation only changes size, since it makes a shape bigger or smaller. So I think you would just leave out the one saying that it has the same size.
Answer: 3a

(5a+2b)
2 Factor out the common term 5a+2b5a+2b.
(5a+2b)(3{a}^{2}-5{b}^{2})(5a+2b)(3a

Step-by-step explanation:
well, we'll be using the distance formula twice here.
that point, is on the x-axis, what's the value of "y" at the x-axis? well y = 0, since it's way down at the 0 level, so the point must be (x , 0).
the distance then from (x,0) to (-3,-1) is the same distance as from (x,0) to 1,6).
![\bf \begin{array}{rcllll} \stackrel{\textit{distance from (x,0) to (-3,-1)}}{\sqrt{(-3-x)^2+(-1-0)^2}}&=&\stackrel{\textit{distance from (x,0) to (1,6)}}{\sqrt{(1-x)^2+(6-0)^2}} \\\\\\ (-3-x)^2+(-1-0)^2&=&(1-x)^2+(6-0)^2 \\\\\\ 9+6x+x^2+1&=&1-2x+x^2+36 \\\\\\ x^2+6x+10&=&x^2-2x+37 \end{array} \\\\\\ 6x+10=-2x+37\implies 8x+10=37\implies 8x=27 \\\\\\ x = \cfrac{27}{8}\implies x = 3\frac{3}{8}~\hfill \blacktriangleright \left( 3\frac{3}{8}~,~0 \right) \blacktriangleleft](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Barray%7D%7Brcllll%7D%20%5Cstackrel%7B%5Ctextit%7Bdistance%20from%20%28x%2C0%29%20to%20%28-3%2C-1%29%7D%7D%7B%5Csqrt%7B%28-3-x%29%5E2%2B%28-1-0%29%5E2%7D%7D%26%3D%26%5Cstackrel%7B%5Ctextit%7Bdistance%20from%20%28x%2C0%29%20to%20%281%2C6%29%7D%7D%7B%5Csqrt%7B%281-x%29%5E2%2B%286-0%29%5E2%7D%7D%20%5C%5C%5C%5C%5C%5C%20%28-3-x%29%5E2%2B%28-1-0%29%5E2%26%3D%26%281-x%29%5E2%2B%286-0%29%5E2%20%5C%5C%5C%5C%5C%5C%209%2B6x%2Bx%5E2%2B1%26%3D%261-2x%2Bx%5E2%2B36%20%5C%5C%5C%5C%5C%5C%20x%5E2%2B6x%2B10%26%3D%26x%5E2-2x%2B37%20%5Cend%7Barray%7D%20%5C%5C%5C%5C%5C%5C%206x%2B10%3D-2x%2B37%5Cimplies%208x%2B10%3D37%5Cimplies%208x%3D27%20%5C%5C%5C%5C%5C%5C%20x%20%3D%20%5Ccfrac%7B27%7D%7B8%7D%5Cimplies%20x%20%3D%203%5Cfrac%7B3%7D%7B8%7D~%5Chfill%20%5Cblacktriangleright%20%5Cleft%28%203%5Cfrac%7B3%7D%7B8%7D~%2C~0%20%5Cright%29%20%5Cblacktriangleleft)
Answer:
= 10x-15-20z
Step-by-step explanation:
5 x 2=10 add the x to the end
5 x 3=15
5 x 4= 20 add the z to the end
Hope this helps (:
