It's D. because you add the powers to get the solution. y x y + y x y = y x y x y x y = y^4
Total marks she'll need to score for an average of 70: 70×5= 350
Score she needs for the 5th test: 350-60-90-90-70=40

The correct equation is:
The volume of second cylinder is 256 centimeter cubed
<em><u>Solution:</u></em>
Given that,
One cylinder has a volume that is 8cm less than 7/8 of the volume of a second cylinder
The first cylinder’s volume is 216 centimeter cubed
From given,
Let "x" be the volume of second cylinder
Therefore,
Volume of first cylinder = 7/8 of the volume of a second cylinder - 8
Thus the volume of second cylinder is 256 centimeter cubed
