Answer:

x=3

Step-by-step explanation:

-2(x+8)+24=11-3x

First distribute.

-2x-16+24=11-3x

Then combine like terms.

-2x+8=11-3x

Add 3x to both sides.

x+8=11

Subtract 8 from both sides.

x=3

Hope this helps!! :P

Answer:

$5x^{2} -18x-8$

Step-by-step explanation:

The formula for area of a rectange is lw, where l is length and w is width. Since x-4 and 5x+2 are the sides, we can multiply them together to give us the area. We do (x-4)(5x+2). We use the FOIL method (First Outside Inside Last) and get 5x^2-18x-8.

x=50

Step-by-step explanation:

angle 1 and 3 are corresponding angles that menas they equal the same

so set it up like this 2x+10=110 solve for x

move over the 10, subtract 10 from 110 you get 100 and divide by 2

you get 50.
