I don't know if this is right but I think it is $4500
By pulling out the common factors for each pair of terms, we can rewrite the original polynomial like this:
3x(2x + 1) + 10(2x + 1)
These two terms now have a common factor of (2x + 1). Seems like we should be able to do something with that information, don't you think? In fact, we can pull out this common factor and rewrite the polynomial again:
1)80
2)55
3)D
4)F
5)-20
6)B
Hope that helps
Answer:
18.75
Step-by-step explanation:
I GOT THIS QUESTION TOO I ACCIDENTALLY PUT THE WRONG ANSWER BUT THE ANSWER IS TOOK HALF IF 16=8
AND TOOK HALF OF 20=10 THAN I TAKE 10x15=150 THAN I
DIVIED WITH 8 WHICH IS [ ANSWER: 18.75 cm ] I THINK ITS RIGHT!!
Step-by-step explanation:
x² = 16
x = ±√16
x = ±4
