The side length of a square is x+1. write an expression that is equivalent to the perimeter of the square.

1 answer:

4 0

4x + 4

This is because there are four sides of a square, and each side is x + 1.

x + 1 + x + 1 + x +1 + x + 1 = 4x + 4

Answer: B' (5,8), C' (3,1)

Step-by-step explanation:

You can use the points A' (-1,8) and A (-2,-3) to find how many units point A was translated.

-2 + 1 = -1

-3 + 11 = 8

Then, you simply add 1 to the x-values of points B and C and 11 to the y-values of points B and C to get B' (5,8), C' (3,1).

I hope this helps!

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.
