The answer <span>5 was added to each side.
</span>
x² + 5x + 126 = x² + 17x + 66
____
Subtract x² from both sides:
x² + 5x + 126 - x² = x² + 17x + 66 - x²
5x + 126 = 17x + 66
126 - 66 = 17x - 5x
60 = 12x
x = 60/12
x = 5
Thus, <span>5 was added to each side.</span>
Answer: a=2.72
Explanation:
Move all the terms containing a to the left side of the equation
-0.5a+4.96=3.6
Subtract 4.96 from right side
-0.5a=3.6-4.96
Would be
-0.5a=-1.36
Divide each term by -0.5 and simplify
a= 2.72
X=18 , first you have to rewrite it as fractions then you have to cross multiply the equation , and last divide
<span>gcf(48,56) = 8
