Factor.<br><br> x^2−9x+20<br><br><br><br> Enter your answer in the box.
Zarrin [17]
First, you’d look at what can multiply together to make 20. You can multiply 10x2, 1x20, or 4x5 (or change them so each number is a negative) to make a positive 20. You then must look at which one of these can be added or subtracted together to create -9. Negative 4 and 5 can be subtracted to make -9, so you would factor them out, as well as the x^2, and get the answer (x-4)(x-5).

Answer: (x-4)(x-5)

Mike and Kate plan to save money for their wedding over a 20 month period. They will need to save $8,000 to help pay for the wed
tino4ka555 [31]

Answer:

Correct answer is d: Neither option A nor option B will allow them to meet their goal.

Step-by-step explanation:

Money needed for wedding: 8000 in 20 months

Set aside the same amount each month: 4000 over 12 months

which becomes \frac{4000}{12} = $333.33

Months left: 8


Lets evaluate option A first:

Save $333.33 each month and postpone wedding for two months

so by adding two months: 10 months are left till wedding

Money save in 10 months: 10 × 333.33 = $3333.33

So total will become 4000 + 3333.33 = $7333.33 (Not feasible)


Lets evaluate options B:

Increase the amount of saving by $ 80:

Amount saved each months first year: 333.33

After adding 80: 333.33 + 80 = 413.33(amount saved each month in 8 months)

<em>8 months are left to wedding:</em>

so they will save 8 × 413.33 = $3306.64

Total will become: 4000 + 3306.64 = $7306.64(Not feasible)


<em>So correct answer is d: Neither option A nor option B will allow them to meet their goal. </em>
