I’m very confused on this question. i’m not very good at geometry.

You're probably fine at geometry. This is algebra pretending to be geometry.

The perimeter is the sum of the sides. Geometry part over.

We write the equation:

36 = (2x + 3) + (2x + 3) + 2x

36 = 6x + 6

30 = 6x

x = 5

Lengths of the sides:

common side: 2x+3 = 2(5)+3 = 13

base: 2x = 10

x=5, base=10, common side=13

b 1: 45 am

step-by-step explanation:

its that because if it was in the pm it would be 1345

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.
