Amir has x pieces of $10 notes and twice as many pieces of $2 notes in his wallet. Find the total amount of money he has in his wallet, in terms of x.​

d

step-by-step explanation:

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

lol.

it's ok we all do this sometimes.
