The following do not have a solution:
• 6x+1=3(2x-4)
• -4(x+3)=4(-x-1)
Answer:
240 cubic centimetres
Step-by-step explanation:
volume of the right rectangular prism

-6x+10 would be ur answer :)

To solve this one-step equation you:
1. Substract 9 in both sides of the equation:
In this step is the mistake as Sara gets as result -4x=29 and the corret result of substract 9 in both sides of the equation is 5x=20.
2. Divide both sides of the equation into 5:
Then, the answer that Sara should found for the equation is x=4
Answer:
1936
Step-by-step explanation:
x² + 87 = (x +1)²
x² + 1)² - x² =87
(x² + 2x +1) = 87
2x + 1 = 87 ⇒ x = 44
44² = 1936
