Determine polynomial expressions for the perimeter and the area of the figure shown below
help plz

Perimeter: 4x + 2

The perimeter is equal to 2 times the length plus 2 times the width.

2(x + 1) + 2(x)

2x + 2 + 2x

4x + 2

Area: x^2 + x

The area is equal to the length times the width.

(x + 1)(x)

x^2 + x

Hope this helps! :)

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:

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.
