Split it up
3x^2+12x-5x-20
group
(3x^2+12x)+(-5x-20)
factor
(3x)(x+4)+(-5)(x+4)
undistribute (x+4) like ab+ac=a(b+c)
(3x-5)(x+4)
Answer:
B: 15 hours
Step-by-step explanation:
Since Dara spends 2 hours reading 72 pages, we can conclude that she spends 1 hour reading 36 pages.
Since we are finding how long it would take for her to read 540 pages, we would divide 540 by 36, which is 15.

Answer:
multiplication
Step-by-step explanation:
In math, "X of Y" means that X is multiplied by Y*. Here, you need to figure out what values are being multiplied.
The fraction of claims remaining unpaid after the first month is ...
1 - 4/7 = 7/7 -4/7 = 3/7 . . . . fraction of claims unpaid after month 1
The problem statement tells you 2/3 of these are paid in the second month. That is ...
(2/3) × (3/7) = 2/7 . . . . of the total of all claims
2/7 of all claims were paid in the second month.
_____
* The interpretation of the word "of" will depend on the context. Here, we're referring to X being a percentage or fraction, as in "2/3 of 3/7".
In some uses, the word "of" may signify that X is multiplied by a fraction with Y as the denominator, as in "5 of 8" (meaning 5/8), for example. If Y is an object, the X is still a multiplier, as in "3 of the bags of cement".
I would cut the "h" into parts
Now you have 3 parts to work with
2 times 6 = 12
2 times 2 = 4
2 times 6 = 12
Add them all up
Area = 28 squared
