The answer is (b+2)(a+3)
You have to group each like term but have them be able to separate evenly so when you do the foil method it goes back to the original equation.
8+4p+2q+r=0
27+9p+3q+r=0
64+16p+4q+r=0
P=-9
Q=26
R=-24
0.84(20)=$16.80
700/100=7
7(1.02)=$7.14
$7.14+16.80=$23.94 in total
Answer:
9
Step-by-step explanation:
Set it up as the following -
3:8 = x:24.
Now cross multiply - 3 * 24 = 8x
72 = 8x
Now divide both sides by 8.
9 = x
Just multiply !!
so 1 inch = 5 miles
3.5 inch must be 3.5×5 = 17.5 miles
so the answer is 17.5 miles !!
