Can someone help me and explain how you do this and not only give me the answer?

25, 90

Step-by-step explanation:

5/6

6 x 5 = 30

Therefore, you must multiply 5 by 5 as well.

5 x 5 = 25

Then:

Divide 75 by 5

Multiply 15 by 6

90

Hope this helps

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.
