Idont know if i got it right side i?

problem 2 is correct

Problem 4 is - 2

Step-by-step explanation:

Number 2 is correct, however you obtained it.

Number 4 is almost correct.

Four

4x + 3 = - 5            Subtract 3 from both sides.

4x + 3-3=-5-3        Combine

4x + 0 = - 8

4x = - 8                  Divide by 4

4x/4 = - 8/4           Do the division

x = - 2

answer: 12

step-by-step explanation:

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 !
