Tammy uses 1 3/4 cups of laundry detergent. The number of loads is 4
<u>Solution:</u>
Given that, Tammy uses 1 3/4 cups of laundry detergent per load.
When she was finished doing laundry one day.
She noticed that she had used 7 cups of laundry detergent.
We have to find how many loads did she do?
Now, we know that, Total cups used can be written as:
<em> </em>number of loads x number of cups per each load = total cups used.
Hence, the number of loads are 4.
Y= 4 because when a number is put next to a letter is usally means times/multiply so 7x4= 28

Answer:
x=14
x=−2
Step-by-step explanation:
Factoring x2-12x-28
The first term is, x2 its coefficient is 1 .
The middle term is, -12x its coefficient is -12 .
The last term, "the constant", is -28
Step-1 : Multiply the coefficient of the first term by the constant 1 • -28 = -28
Step-2 : Find two factors of -28 whose sum equals the coefficient of the middle term, which is -12 .
-28 + 1 = -27
-14 + 2 = -12 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -14 and 2
x2 - 14x + 2x - 28
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-14)
Add up the last 2 terms, pulling out common factors :
2 • (x-14)
Step-5 : Add up the four terms of step 4 :
(x+2) • (x-14)
Which is the desired factorization
