1. if a = 16 and b= 12, find c

klasskru [66]

Answer:

Step-by-step explanation:

The pythagorean theorem states that

$a^2+b^2=c^2$

So $16^2 + 12^2 = c^2\\256+144 = c^2\\400 = c^2$

You would then do

$400 = c^2\\\sqrt{400} = c$

Because a square root is the opposite of a square.

$\sqrt{400} = 20$

because 20 * 20 = 400

Find the greatest common factor of 14y^2 and 15y^4

matrenka [14]

Answer:

I have to say, I was a bit stumped on this one for some reason, but I believe your answer is y^2.

Step-by-step explanation:

All four variables , (14, 15, y^2, & y^4) should all have a common denominator, but I only see similarities in y^2 with y^4 and 14 with 15, but the y's can be understood ones. Multiply your common variables and get y^2. Could someone check me in that though?
