Answer:
(x−3)(x+8)
Step-by-step explanation:
The middle number is 5 and the last number is -24.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get 5
Multiply together to get -24
Can you think of the two numbers?
Try -3 and 8:
-3+8 = 5
-3*8 = -24
Fill in the blanks in
(x+_)(x+_)
with -3 and 8 to get...
(x-3)(x+8)
The first one would be 12+14+18+12+15. She biked about 71 miles.
I did this by rounding the decimal places. 5 and up = round up. 4 or less= stays the same. I'll answer #2 in a second, I have to do something :)
