How can you inscribe a regular polygon in a circle?

For a shape to be inscribed means that it's area is smaller than that of the other shape. Essentially, it's one shape inside another.

View my crudely drawn example for visualization. There, the square-ish shape is inscribed in the circle.

(You can basically inscribe any shape within another.)

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5

step-by-step explanation:

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
