1/2 (2x + 1) = 3
Solve for x

To solve for x, you need to isolate/get the variable "x" by itself in the equation:

  Multiply the reciprocal of 1/2 on both sides, which is 2/1 or 2

2x + 1 = 6        Subtract 1 on both sides

2x + 1 - 1 = 6 - 1

2x = 5         Divide 2 on both sides to get "x" by itself

18.8 cubic inches.

step-by-step explanation:

volume of a cone = πr²h

r = 1.5 inches

h = 8 inches

pi = 3.14

volume of our cone = × 3.14 × 1.5² × 8 = 18.84 square inches

or equals to 18.8 square inches rounded up to nearest tenth.

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
