Quantitative observations measure the quantity, or the amount, of a certain thing. Therefore they must always use a number value to measure the amounts, and a unit to signify what the amount is for.
By either long or synthetic division, it's easy to show that

The quartic will be exactly divisible by

when the numerator of the remainder term vanishes, or for those values of

such that

I'm not sure how to count the number of solutions (software tells me it should be 80), but hopefully this is a helpful push in the right direction.
Answer:
See Below
Step-by-step explanation:
150 = p + 78 ------ you want to get the p to one side and the other number the the other side of the =
(78 - 150) = p (78 - 78) ---- what ever you do to one side you do to the other
72 = p
s - 51 = 12 (same thing as above)
s (-51 + 51) = 12 + 51
s = 63
65 = blank + 7 ( you can put a letter like x or y because they number is not determined yet)
65 = x + 7 (same as above)
( 7 - 65 ) = x ( 7 - 7 )
58 = x
Answer:
hi
Step-by-step explanation:
A is 50 and B is 10
then, C is 5
