2 + 3(x + 2x) = −2x(2 − 4) + 1

A) −5
B) −
1
5
C) 5
D)
1
5

B -1/5

you have to follow pemdas first get rid of the parethase which leaves you with 2+3x+6x=-4x+8x+1 then you add what you can do then you get 2+9x=4x+1 then you subtract 2 from both sides and subtract 4x from both sides which leaves you with 5x=-1 then you divide 5 from both sides and get x=-1/5

Step-by-step explanation:

For this case we can model the problem as a cylinder.

The volume of a cylinder is given by:

Where,

Ab: base area

h: cylinder height

The volcano is 46 centimeters tall and has a

volume of 800 cubic centimeters.

Substituting values in the equation we have:

From here, we can clear the area of the base

An equation that can be used to find the area of the circular base is:
