3a^2+5a-2.
To do this problem would require a method called FOIL. If you are not familiar this means First Outside Inside Last. You multiply the First terms, 3a and a, which results in 3*a*a or 3a^2. Next you multiply the Outside terms, a and -1, which results in -a. Next multiply the Inside terms, 2 and 3a, to result in 6a. Finally multiply the Last terms, 2 and -1, which gives us -2. If we put all these terms together we get 3a^2 -a +6a -2 which we can then simplify to 3a^2+5a-2
Answer:
<u>x= 35 hot dogs</u>
<u>y= 52 soda</u>
Step-by-step explanation:
x= hot dogs
y= soda
Total sold
1 x + 1 y = 87 .............1
2 x 0.50 y = 78.50 .............2
Eliminate y
multiply (1)by -0.50
Multiply (2) by 1.00
-0.50 x -0.50 y = -43.50
2 x + 0.50 y = 78.50
Add the two equations
1 x = 35.00
/ 1
x = 35.00
plug value of x in (1)
1 x + 1 y = 87
35 + y = 87
y = 87 -35
y = 52
y = 52.00
x= 35 hot dogs
y= 52 soda
