Answer:
How old is his son... It's impossible to tell unless you give the sons age.
Step-by-step explanation:
the equation though would be 5x (x is the sons age)
Answer:
Factored form...
Step-by-step explanation:
Foil out (x-4)(x+2)=16
First: x*x=
Outer: 2*x=2x
Inner: -4*x = -4x
Last: -4*2 = -8
Combine them all:
Simplify:
What multiplies together to make -24 but adds together to make -2?
Lets list the factors of -24 to decide:
1 x -24
2 x -12
3 x -8
4 x -6
-6+4 = -2
Therefore...
Answer:
n=6
Step-by-step explanation:
n= the amount of boxes he needs
so if he puts 30 toys in each box out of 180 you divide 180 by 30 and you get your answer.
so the amount of boxes he needs = 6
If you want to take 20% off $9, you must find 80% of $9. As 100% - 20% = 80%.
80% turns out to be 4/5, 8/10 or 0.8.
8/10 x 9
= 72/10
= 7.2

Answer:
$7.20
This is the simplified version 6x^2+9x+3.
