The correct answer is Option C. Ty saved $14 and he earns $9 each week. How many weeks will it take till he has $100?
Further explanation:
Given equation is:
9x+14
We will look at the options one by one
<u>A.9 dogs and 14 dogs and 14 cats cost $100</u>
If this option has to be considered, there will be atleast two variables involved one for the dogs and one for the cats while the given equation only involves one variable so this is not the correct option.
<u>B. Ty wants to buy 14 dogs, but they cost $100, how much more does he need?</u>
The given scenario cannot be linked to given equation if x represents dogs the equation will be something like 14x=100 so this option is not the correct answer.
<u>C. Ty saved $14 and he earns $9 each week. How many weeks will it take till he has $100?</u>
The number 14 will be constant as this is the value which is used only once while ty earns 9 dollar per week if x represents number of weeks then the equation to represent the scenario will be
9x+14=100
The value of x will give us the number of weeks required.
The correct answer is Option C. Ty saved $14 and he earns $9 each week. How many weeks will it take till he has $100?

Answer:
16
Step-by-step explanation:
Perfect square in the quadratic from ax² + bx + c
You know an equation is perfect when:
2√(ax²)√(c) = bx
Substitute x² for ax² and 8x for bx. Then isolate c by doing the reverse operations.
2√(ax²)√(c) = bx
2√(x²)√(c) = 8x
2x√c = 8x Divide both sides by 2x
√c = 4 Square both sides to isolate c.
c = 16
The missing constant term is 16.
Check answer:
x² - 8x + 16
(x - 4)²
= (x - 4)(x - 4)
= x² - 4x - 4x + 16
= x² - 8x + 16
