Answer:
15/s
Step-by-step explanation:
15 caps ÷ s = 15/s caps per swimmer
The inequality used to solve for x is x=750/15
Side of the room = x.
From the right triangle, where sides of the square are legs of the right triangle, and the diagonal of the square is a hypotenuse of the right triangle.
x²+x²=6²
2x²=36
x²=18
x=√18 =√(2*9)=3√2≈4.2m
Answer: -22
Step-by-step explanation:
In the first question, we can simplify 2√8 to 4√2, making it :
(√10 + 4√2)(√10 - 4√2)
When you FOIL, √10(√10) = 10, and 4√2 * -4√2 = -32. The others cancel each other out. So -32 + 10 = -22.
