To complete the square, the second degree term must have a coefficient of 1.
Since the second degree term here has a coefficient of 4, we start by dividing each term on both sides by 4.



Now we can complete the square.
First, we need to find what number completes the square.
We take the coefficient of the first degree term, -7 in this case.
Divide it by 2 and square it. -7 divided by 2 is the fraction -7/2.
Now we square -7/2 to get 49/4.
We add 49/4 to both sides.

You should just have to divide the weight lost (4.5 ounces) by the time it took for her cat to lose that weight (4 weeks)!
4.5 / 4 = 1.125, meaning her cat lost about 1.125 ounces per week!
Answer:
-14/3
Step-by-step explanation:
25=9x+74-7
25=9x+67
-42=9x
-42/9=9x/9
-42/9=x
-14/3=x
