Answer:

5units

Step-by-step explanation:

Given the two vertices of a rectangle at (3,2) and (8,2). We are to calculate the distance between the two points.

Using the formula

D = √(x2-x1)²+(y2-y1)²

D = √(2-2)²+(8-3)²

D = √0+5²

D = √25

D = 5

Hence the length of the side of the rectangle is 5units

5(x+2)-7=3x+5 Please give step by step explanation

Brums [2.3K]

Answer:

x = 1

Step-by-step explanation:

Solve using inverse operations

5 ( x + 2 ) - 7 = 3x + 5

first distribute the 5

5x + 10 - 7 = 3x + 5

simplify the expression

5x + 3 = 3x + 5

Inverse operations, then simplify

5x + 3 = 3x + 5

-3 -3

5x = 3x + 5 - 3

5x = 3x + 2

-3x -3x

2x = 2

/2 /2

x = 1

The surface are of a cylinder is given by the formula SA=2pir^2+2pirh,where r is the radius of the base of the cylinder and h is

UNO [17]

Answer:

$h=\frac{SA}{2\pi r}-r$

Step-by-step explanation:

The surface area of a cylinder is equal to

$SA=2\pi r^{2} +2\pi rh$

Solve for h

That means ----> isolate the variable h

subtract 2πr² both sides

$(SA-2\pi r^{2})=2\pi rh$

Divide by 2πr both sides

$\frac{SA-2\pi r^{2}}{2\pi r}=h$

Rewrite

$h=\frac{SA-2\pi r^{2}}{2\pi r}$

Simplify

$h=\frac{SA}{2\pi r}-r$
