Answer:
=12x+y
Step-by-step explanation:
Combine like terms
=5x+-3y+7x+4y
=(5x+7x)+(-3y+4y)
=12x+y
3×9=27-2=25
3× what # - 2= 25
Green or purple = 10
prob(green or purple) = 10/30 = 1/3
Answer: 92.5 inches by 100 inches.
Step-by-step explanation:
1. You know that 1 inch represents 8 feet and the dimensions of the building are 740 feet by 800 feet, therefore, you must apply the proccedure shown below:


2. Then, as you can see, the dimensions of the building on the drawing are 92.5 inches by 100 inches.
Ln ( a^(-4) / b^1 c^1 ) =
= ln a ^(-4) - ( ln b + ln c ) =
= - 4 ln a - ln b - ln c =
= - 4 * 2 - 3 - 5 =
= - 8 - 3 - 5 = - 16
