Two multiply 2 monomials, you have to multiply the coefficients and add the degrees. For example
2x^2 × 3x^3 =
6x^5
The volume of air needed is equal to the volume of the sphere, which is 7,234.56 cm^3.

How to get the volume of a sphere?</h3>
The volume of air that we need is equal to the volume of the basketball.
Remember that for a sphere of radius R, the volume is:
V = (4/3)*3.14*R^3
In this case, the radius is 12cm, replacing that we get:
V = (4/3)*3.14*(12cm)^3 = 7,234.56 cm^3
Then, to fully inflate the ball, we need 7,234.56 cm^3 of air.

It is a trick question 13+13 DOES equal 26
Answer:
1.D
2.B
Step-by-step explanation:
For the first one divide see which one is less which is D
For the second one Ive always used the method kcf keep change flip so you keep 
the change ÷ to multiplication so then flip 
so the equation would be
x
so multiply the 15 by 9 then you get 135 then divide by 2 so thats your answer
