8x + 11 = 2(4x - 7) + 25<br> Step by step please!
Dimas [21]

Step-by-step explanation:

8x + 11=2(4x-7) + 25

8x + 11 = 8x - 14 + 25

8x + 11=8x- 14 + 14 +25 + 11

8x-8x + 11 -11 = 14 + 25 + 11

8x-8x =14 + 25 + 11

X = 50

How do the lateral and total surface area of a cylinder differ ?
vichka [17]
The lateral surface area of a cylinder is just the long side connecting the bases, whereas the total surface area includes both the lateral surface area and area of the two circular bases.

SA_l_a_t=2 \pi rh (Imagine a rectangle with the circumfrence of the base as one side and the height as the other being folded around)

SA = 2 \pi rh + 2 \pi r^2 (Plus the area of two circles)

The literal difference between surface areas would be the two bases 2πr² if you need that.
