Answer:
3 + x for both. They did the same amount.
Step-by-step explanation:
Will volunteered 3 hours in march. In April, he volunteered the same amount plus the same amount at Lydia did in March. Since we don't know Lydia's then this is x. So in April, Will volunteered 3 + x.
Hector volunteered 5 hours in March. But in April, he volunteered 2 less than March which 5-2 = 3. Plus he did the same amount as Lydia in March. So his expression is 3+x.
Will and Hector did the same amount of hours.
Its going to be a lot of steps
Step one
To complete the square, the same value needs to be added to both sides
f(x)+?=x^2 -9x+?+14
Step two
To complete the square add to the expression
x^2 -9 + 81/4= ( x- 9/2 ) ^2 add 81/4
To the expression
f(x)+?=x^2 -9+ 81/4 + 14
Step three
Since 81/4 was added to the right-hand side, also add 81/4 to the left-hand side
f(x)+81/4=x^2 -9x+81/4+14
Step four
Use a^2-2ab +b^2 = ( a-b)^2 to factor the expression
f(x)+81/4=(x-9/2)^2+14
Step five
Move the constant to the right-hand side and change its sign
f(x)=(x-9/2)^2 + 14- 81/4
Last step
Calculate the difference
F(x)=(x-9/2)^2 -25/4
That was to long
