Answer

-1,11

step by step

when x =11

3|x-5|=20

3|11-5|+2=20

3|6|+2=20

18+2=20

20=20

when x=-1

3|-1-5|+2=20

3|-6|+2=20(the -6 became 6 due to | | sign)

3*6+2=20

18+2=20

20=20

$\bf p(x)=x^4-256\qquad \boxed{2^8=256}\qquad p(x)=x^{2\cdot 2}-2^{4\cdot 2}
\\\\\\
p(x)=(x^2)^2-(2^4)^2\implies p(x)=[x^2-2^4]~[x^2+2^4]
\\\\\\
p(x)=[x^2-(2^2)^2]~[x^2+2^4]\implies p(x)=[(x-2^2)(x+2^2)]~[x^2+2^4]
\\\\\\
p(x)=(x-4)(x+4)(x^2+16)$

It’s for my geometry class and I don’t know how to solve it. Can someone please help me?

Answer:

Below in bold.

Step-by-step explanation:

Because the 2 sides marked with the double lines are equal:

5y-1 = 2y+11

3y = 12

y = 4.

Also :

3x-5 + 2(2x+5) = 180

3x - 5 + 4x + 10 = 180

7x = 180 + 5 -10

7x = 175

x = 175/7 = 25.
