Answer:
620
Step-by-step explanation:
7 is near 10 so you round to the next number on the 10 table
A=2916, you take 54 and square it
Answer:

Step-by-step explanation:
Another way to look at this question is: We make 5/6 yards of fabric from each pair of shorts. How many shorts do we need to make 35 yards of fabric.
So, we need to solve this equation for
:
.
We can multiply both sides of the equation by
to get
.
We then divide by
on both sides to get
.
So, we can make
pairs of soccer shorts.

32.6 = 17.3 + -1d
Solving
32.6 = 17.3 + -1d
Solving for variable 'd'.
Move all terms containing d to the left, all other terms to the right.
Add 'd' to each side of the equation.
32.6 + d = 17.3 + -1d + d
Combine like terms: -1d + d = 0
32.6 + d = 17.3 + 0
32.6 + d = 17.3
Add '-32.6' to each side of the equation.
32.6 + -32.6 + d = 17.3 + -32.6
Combine like terms: 32.6 + -32.6 = 0.0
0.0 + d = 17.3 + -32.6
d = 17.3 + -32.6
Combine like terms: 17.3 + -32.6 = -15.3
d = -15.3
Simplifying
d = -15.3</span>
By looking at the formula you can see that the quadratic part is 0 if you fill in x=3 (you know, 3-3 = 0). The outcome of the formula then becomes y= 0+5.
That gives us point (3,5) as the top of the parabola. So there you go, answer A.
