2^m×2^n=2^-6 and determine which values of m and n are solutions are solutions

Gnoma [55]

Remember
$(x^m)(x^n)=x^{m+n}$
and
if $x^m=x^n$ where x=x then m=n
so
$(2^m)(2^n)=2^{m+n}=2^{-6}$
so
m+n=-6
so test the options

first one works
2nd ones doesn't
3rd one doesn't
4th one doesnt'

answer is first option, m=3 and n=-9

PLEASE ANSWER! (BRAINLIEST)

gavmur [86]

First, find the distance AB by the formula:

$AB=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}.$

If A(0,-7) and B(8,8), then

$AB=\sqrt{(8-0)^2+(8-(-7))^2}=\sqrt{8^2+15^2}=\sqrt{64+225}=\sqrt{289}=17.$

Dilating polygon ABCD by a scale factor of 2 with the center of dilation at the origin to create polygon A′B′C′D′, you increase the distance AB twice, A'B'=2AB. Thus, A'B'=2·17=34 units.

Answer: AB=17 units, A'B'=34 units.
