A trinomial is a polynomial with three terms. It can be determined if it is a difference of two squares when you factor it.
The resulting factor of a trinomial that is a difference of two squares is: a²<span> – b</span>²<span> = (a + b)(a – b) or (a – b)(a + b)</span>
You will notice that the middle term is missing. This means that the middle term zeroes out as a result of having the same number of different signs (+ and -)
468 plus 624 times 7 divided by 4 and you should get the amount of water in the two tanks
St meaans s times t
s=-4
t=9
st=-4 times 9
negative times positive=negative
4 times 9=36
-4 time s9=-36
st=-36
answer is -36
The inequality x < 9.7 tells us x needs to smaller than 9.7.
A number like 5 will be fine. Because 5 < 9.
But someone like 10 won't be fine.
Because 9 < 10.
Even 9.7 won't be suffice.
Because 9.7 < 9.7 does not make sense. If it was 9.7 <= 9.7 then it would be fine.
First thing we gotta do is find the unit rate:
800 divided by 2.5 = 320
And now your problem is complete! The unit rate or square foot per hour is 320 square feet per hour!
