Answer:
x=<u>-2y+70</u>
5
y=<u>-5x+70 </u>
2
Step-by-step explanation:
the square of a negative number always be positive
eg: -2² = -2×-2 = (-×- = +) +4
the cube of a negative number always be positive
eg: -2³ = -2×-2×-2 = (-×-×- = +) -8
hope it helps...!!!
If this is correct the answer would be
y^2 + 0.1y + 0.0025

Divide both sides by 25 to isolate x:
<em>If the radius of a sphere is doubled, the surface area becomes four times the original surface area.</em>
