This is a pythagorean theorem problem

When solving for the sides of a right triangle... a^2 + b^2 = c^2

Therefore, 7^2 + b^2 = 25^2

b^2 = 25^2 - 7^2 = 576

b = sqrt(576) = 24

What is 4 multiplied by 4/6

yawa3891 [41]

Okay,

1. Multiply 4 x 4.

2. Then Since 4 x 4 is 16 it would be 16 over 6 ( $\frac{16}{6}$ )

3. Then Simplify, 6 can go into 16 twice, being 12.

4. There is 4 left over, so put 4 over 6 ( $\frac{4}{6}$ )

5. Finally, simplify again, 4 can be divided by 2, so can 6, make it 2 over 3 ( $\frac{2}{3}$ )

Answer: 12 and 2 over 3 ( $12 \frac{2}{3}$ )
