- - Lets solve for G.
Keep in mind: G is acting as a unknown variable, commonly used as "x"
So we need to find the variable, and then we solve for g until we get "0" for our problem.
Okay so lets start off by factoring our equation, in this case you do left first.
Alright, now we can set out "o" as the equal to all of our factors.

And now you need to solve for that,
And you get -1 for our answer.
Final answer: g=-1
Answer:
The square root function
sqrt(144) or √144 produces a single positive value, 12.
However if you have an equation
x² = 144, then you have two possible values for x, 12 and -12.
Two ways to look at it.
x² - 144 = 0
Difference of two squares
(x+12)(x-12) = 0
x = -12, 12
x² = 144
x = ±√144
x = ±12
x = -12, 12
Answer: the amount by which her lunch account would have been impacted is $45
Step-by-step explanation:
Each day Valerie charges her lunch account for her lunch. If the cost of lunch is $3 then, it means that Valerie charges the lunch account with $3 daily. It means that in x days, she would have charged her lunch account with 3×x = $3x
If she charged her account for a period of 15 days, it means that x = 15. Therefore, the amount by which her lunch account would have been impacted is 3×15 = $45
