2. 5x^2 x (3x+5)
3. 3x^3 x (3x^4 +11)
This question asks what is half of 45.
45 divided by two equals 22.5
The car will travel 22.5 miles in .5 hours.
To start off you need to figure out how much money each item costs. Now get out your calculator because it will make this process go much faster.
EXAMPLE:
If your sodas cost $2.25 EACH you need to do the following math equation
2.25 X 3 = 6.75 witch is the total you would be paying in this situation.
HOT DOGS EXAMPLE:
Lets say that your hotdogs are $4.75 PER DOG. You just need to follow the same steps above.
4.75 X 2 = 9.5 but thats not how we write money so it would be $9.50
Hope this helps,

Answer:8
Step-by-step explanation: she makes $100 a day so you would subtract that from the total (276) then you would divide the remainder (176) by the amount she makes an hour (22) then you would end up with 8 hours
Answer:
Area: 6a^2
Perimeter: 12a^2
Step-by-step explanation:
To find the area of a triangle, use the formula A=1/2 b*h. The base is 3a^2 and the height is 4a^2.
A= 1/2 (3a^2)(4a^2)
A = 1/2 (12a^4)
A = 6a^4
To find the perimeter of the triangle, add each of the sides of the triangle. The third side, the hypotenuse, can be found using Pythagorean theorem.
Now add each of the sides: 3a^2 + 4a^2 +5a^2 = 12a^2
