Simplify 3/5p tp 3p/5

4 + 2p = 10(3p/5 - 2)

Expand

4 + 2p = 6p - 20

Subtract 2p from both sides

4 = 6p - 20 - 2p

Simplify 6p - 20 - 2p to 4p - 20

4 = 4p - 20

Add 20 to both sides

4 + 20 = 4p

Simplify 4 + 20 tp 24

24 = 4p

Divide both sides by 4

24/4 = p

Simplify 24/4 to 6

6 = p

Switch sides

A cylinder has a height of 7cm.

valina [46]

We first need to find the radius of the circle, so we need to do 8π/π which gives us a diameter of 8 cm, halving this gives us a radius of 4 cm.

The area of this circle will be:

A = πr^2

A = 4^2

A = 16π cm^2

Now to find the volume we simply multiply the area by the height:

16π × 7 = 112π cm^3 which is our final answer.

K^2+5k-6=0 quadratic formula

s2008m [1.1K]

I hope this helps you

1.k^2+5k-6=0

a=1

b=5

c= -6

disctirminant =b^2-4ac

disctirminant =5^2-4.1. (-6)

disctirminant =49

x1= -(5)+ square root of 49/2.1

x1=-5+7/2

x1=1

x2= -5- square root of 49/2.1

x2= -5-7/2

x2= -6
