I SAY IT THE SECOND OPTION
Answer:
Step-by-step explanation:
The diagonal of any square with side length 
is equal to 
. Since the side length of the square is 10, the diagonal must be 
.
To support and prove this:
The diagonal creates two 45-45-90 triangles, with the diagonal being the hypotenuse of both of these triangles. The Pythagorean Theorem states that in any triangle, the sum of the squares of both legs is equal to the square of the hypotenuse (
).
Call the diagonal 
. In these two triangles, both legs are equal to 10 (the side lengths of the square), and the hypotenuse is the diagonal. Thus, we have:
Answer:
4y = -x + 9

Answer:
Step-by-step explanation:
Commutative property of addition: The order in which you add these fractions together doesn't matter.
I would combine 3/5 and 2/5 first, as that readily results in 5/5, or just 1.
Then we have 1 1/4, or 1.25, or 5/4 as the final answer.
I would say the answer is D, since the sample only shows that customers on Mondays were surveyed, and says nothing about other customers on different days.
