Answer:
A
Step-by-step explanation:
The number of different combinations is the number of different type of each items multiplied together.
To select bundles of "backpack", "binder", "pencil", & "notebook", we see how many different type of each are there and just multiply them. Hence:
"There are 5 types of backpacks, 5 types of binders, 3 types of pencils, and 2 types of notebook paper"
So, 5 * 5 * 3 * 2 = 150
The correct answer is A

Note: Before solving this type of question we should have proper knowledge of natural numbers, rational numbers and irrational numbers.
Answer:
15(2r^2+2r+5)
Step-by-step explanation:
I'm more of a guess and check type of person, but 15 x 2r^2 = 30r^2, 15 x 2r = 30r, and 15 x 5 = 75
