Hello,
if 2x²=54 then (2x)²=4x²=2*2x=2*54=108
Divide 4 by 1, you get 4. Divide 120 by 4, get 30. Hope this helped!
Answer:
3/8
Step-by-step explanation:
divide out the 4's and you are left with 3/8
Add like terms on the same side:
-10 + 8x = -56
Add ten to both sides
-10 + 8x + 10 = -56 +10
Simplify:
8x = -46
Divide both side by 8
8x/8 = -46/8
Simplify
x = - 5.75
The answer is x = -5.75
(The answer can also be written as -23/4 or -5 3/4)
