Answer:
C: isolate the x squared by using inverse operations
Step-by-step explanation:
This method of solving quadratic equation is used when there is only x² term and no x term. Thus;
For example, we have a quadratic equation;
x² - 1 = 80
To solve this by square root method, the first step we have to take is to isolate the x² term by inverse operation which is by addition of 1 to both sides to get rid of the -1 on the left side so that x² can be isolated.
First step is Add 3 to both sides

1 cm = 10 mm
? cm = 987 mm
987/10 = ? cm = 98.7 cm.
There are 98.7 cm in 987 mm.
Answer:
Our score = 0.60, Amanda's score = 0.25
Step-by-step explanation:
For Amanda
μ = 15 , σ = 4
z- score for X = 16 is (From z table)
z = (X - μ)/σ = (16 - 15)/4 = 0.25
For us
μ = 310 , σ = 25
z score for X = 325 (From z table)
z = (325-310)/25 = 0.60
Since our z score is better than Amanda's z score, we can say we did better
2000-1996=4 forks
2000-1745=255 knives
since there are extra spoons it is reversed-->2116-2000=116 spoons
the owner needs 4 forks,255 knives and there are 116 extra spoons
