(3x + 14) (3x + 14) = 9x^2 + 24x + 16
Answer:
208 minutes = 3.47 hours
Step-by-step explanation:
It takes each person 10.4 minutes for 1 wall. So 20 people would take 208 minutes for 20 people to paint 20 walls
52/5 = 10.4
20 x 10.4 = 208
18^2 + 68^2 =
= 324 + 4,624
= 4,948
74^2 = 5,476
4,848 is not equal to 5,476.
Since the sum of the squares of the lengths of the two shorter sides is not equal to the square of the length of the longest side, the triangle is not a right triangle.
I think the answer is c but I am not for sure
