What is -4(7x+5)=-160

Mathematics

stiks02 [169]3 years ago
7 0

To get rid of the parantheses we must multiply -4 times anything inside the parantheses.

<em>-4(7x+5)=-160</em>

<em>-28x-20=-160</em>

Add 20 to both sides of the equation.

<em>-28x-20=-160</em>

<em>-28x=-140</em>

Divide both sides by -28

<em>-28x/-28=-140/-28</em>

<em>x=5</em>

<em>Our final answer is 5 </em>

Hope this helps!

After inputting the values you get:
SA = 2(7)(10) + 2(10)(5) + 2(7)(5)
and after simplifying:
SA = 140+100+70
SA=310
