-X - 4x
I need help help me plz

-5x

Step-by-step explanation:

When given two numbers to subtract and the numbers both have the negative sign .

Negative negative gives positive. So , you add the numbers . Also, the result carry the sign attached to the highest number .

Given -x -4x

Add both and attach the sign attached to the highest value to the result.

The highest is 4x and the lowest is x .

x + 4x = 5x

Add - sign

It becomes-5x

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
