HELP ME PLEASE!!! I DON'T UNDERSTAND!

Answers

Answer 1

Answer: 12

Step-by-step explanation:

this is a right angled triangle so you use the pythagorean theory

which is a^2 + b^2 = c^2

you have c and b already. c is the hypotenuse.

a^2 + 16^2 = 20^2

a^2 + 256 = 400

a^2 = 400 - 256

a^2 = 144

then you square root 144 and get..

a = 12

Answer 2

Answer:

I believe that the answer is 12 but find someone who knows for sure.

Victor baked 30 chocolate chip cookies, 18 peanut butter cookies, and 24 sugar cookies. He wants to split them into equal and identical bags to sell at the bake sale. What is the greatest number of bags of cookies Victor can make?

Answers

Answer:

Step-by-step explanation:

The greatest common factor (GCF) of 18, 24, and 30 is 6. :)

Victor can make at most 6 bags with equal numbers of each type of cookie.

_____

18 = 6×3

24 = 6×4

30 = 6×5

One way to look for the GCF is to consider the differences between the numbers. The smallest difference between any pair is 6, which also divides all of the numbers evenly. Hence 6 is the GCF.
