exponents
8^2=64
4^2=16
now we have
2(4)(64)-16
multiply
2(4)=8
8(64)=512
now we have
512-16
subtract

For the following right triangle, find the side length . Round your answer to the nearest hundredth

vlada-n [284]

Step-by-step explanation:

Since we have 90° angle that means that side opposite of it is hypotenuse, so it goes:

a=10cm b=6 c=?

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

${10}^{2} = {6}^{2} + {c}^{2} \\ \\ 100 = 36 + {c}^{2} \\ \\ {c}^{2} = 100 - 36 \\ \\ {c}^{2} = 64 \\ c = \sqrt{64} \\ c =8$

Which answer expresses the ratio as a fraction in simplest form?

jolli1 [7]

First we need to find the gcf (greatest common factor) of 18 and 24

in this case it would be 6, since it’s the highest number you can divide both 18 and 24 by without leaving you with a remainder

then we divide both 18 and 24 by 6, leaving you with 3/4

hope i helped!
