Answer:
(x+4)(x+5)
Step-by-step explanation:
Before we figure out the problem, we must know that the two numbers in the expression must equal the middle number when added and that when multiplied they must equal the last number.
To do this, we list the multiplies of 9 and 20.
9: 1,9,3
20:1,20,2,10,4,5
From there, you go through both lists and follow the given rules stated at the top. When you do that you get, <u><em>(x+4)(x+5)</em></u>.
To check this answer, you can do a various amount of proofs but the most effective one to me is the F.O.I.L. (first, inner, outer, last) and voila.
Answer:
450 banana cream pies
Step-by-step explanation:
Total number of pies in a month = 1500;
this represents 100% of the pies
Out of the total pies in a month, the proportion of banana cream pies = 30%
Next, find the number of banana cream pies ;
# of Banana pies = proportion of banana pies * total number of pies
=30% *1500
= 450
Therefore, the banana cream pies sold were 450.

3/4(24-8x)-16=-2/3(6x-9)
multiply 24 and 3/4 which equals 18 and then -8x times 3/4 which equals -6x
then foil again on the other side
-2/3 times 6x equals -4 then -2/3 times -9 equals 6
18-6x-16=-4x+6
combine like terms
2-6x=-4x+6
+6x +6x
2=2x+6
-6 -6
-4=2x
divide 2 on both sides
-2=x
