Find the length of the unknown side. round your answer to the nearest whole number 12m and 8m

hi there!

the correct answer to this question is: 8.94 or sqrt{80}

Step-by-step explanation:

you use Pythagorean theorem: a^2 + b^2 = c^2

12^2 = a^2 + 8^2  

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
