8.94

Step-by-step explanation:

with a right triangle, you can use the Pythagorean Theorem, a^2 + b^2 = c^2

if you put in the values that you have, which are 8 and 4 into the equation, you get 8^2 + 4^2 = c^2

Now simplify, and you get 16 + 64 = c^2 which can then be further simplified to 80 = c^2

To get the value c all by itself, you have to square both sides. Square root of 80 becomes 8.94, and square root of c^2 becomes just a 'c'.

Therefore, you get 8.94 = c, meaning that the missing length (hypotenuse) is 8.94 units long.

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
