Answer:
(x + 9)(x + 2 )
Step-by-step explanation:
Sum =11
Product = 18
Factors = 9 , 2
When you multiply (9*2 = 18) and when you add (9 +2 = 11).
x² + 11x + 18 = x² + 9x + 2x + (9*2)
=x(x + 9) + 2(x + 9)
= (x + 9)(x + 2 )
So we start out by finding out what 80% of 500 is by,
500 * .80 = 400
So if 80% is 400 that means that there is still space available for 100 more gallons!
How the heck did we know that?!?
simple 500- 400= 100
So that leaves us knowing that there are 100 gallons left that can be held!! :)
So your answer is 100 gallons!!
I hope that this helped!
Answer:
-3/56
Step-by-step explanation:
-1/5 ab
Let a = 3/7 b = 5/8
-1/5 * 3/7 * 5/8
Rewriting
-1/7 * 3/8 * 5/5
Canceling like terms and multiplying
-3/56
Answer:
C
Step-by-step explanation:
We need to first rewrite the equation the proper way.
(-2x+4x²+5)-(x²+3x)
We need to distribute the negative thought the 2nd set of parenthesis.
-2x+4x²+5-x²-3x
combine the same terms
3x²-5x+5
