PLSSSSSS HELP <br> BRAINLIST
Helga [31]

Answer:

The step 4 is not what he should have done. But the wrong is step 5, because if he added -2x both sides, it would give the following equation:

x-12=-4x+6

and not x-12=6

Note that in step 4 he should have added 2x and not -2x to both sides, but we still have the equality. The problem is that step 5 is totally wrong.

I don't know what answer is expected to this question, but I would mark step 5, because this is mathematically wrong.  

Solving the equation

3(x-4)=-4-2(x-5)

Using distribution

3x-12=-4-2x+10\\3x-12=-2+6

Add 2x both sides

3x-12+2x=-2x+6+2x

5x-12=6

Add 12 both sides

5x-12+12=6+12\\5x=18

Divide both sides by 5

$x=\frac{18}{5} $

Help The area of a square
DIA [1.3K]

Answer:

2551\dfrac{1}{2}

Step-by-step explanation:

\bf l = 20\dfrac{\sf 1}{4} \ in = \dfrac{81}{4} \ in

\bf w = 10\dfrac{1}{2} = \dfrac{21}{2} \ in\\\\\\h = 12 \ in

Volume of rectangular prism = l*w*h

                                                 = \dfrac{81}{4}*\dfrac{21}{2}*12\\\\\\= 81 *\dfrac{21}{2}*3\\\\\\= \dfrac{5103}{2}\\\\\\= 2551 \dfrac{1}{2} \ cubic \ inches
