Answer:
405 
Step-by-step explanation:
Area of a triangle =
Base * Height
* 30* 27 = 405 
Input values must have exactly one output value in order for the function to remain a function.
d. 2
f. 8
g. 15
If we had AB: BC: CD, we could easily have solved that problem. In order to combine these ratios, we need to have the same number for BC. We can create this number by finding LCM (Least Common Multiple) for 5 and 3, which is 15. Then, we can write ratios of AB:BC = 6:15 and BC:CD=15:20. Now, we can easily combine these ratios. AB:BC:CD = 6:15:20. Then, 6k+15k+20k = 82 and k=2 cm. And BC = 30 cm
Answer:
To find the answer you just have to solve 4(x-3)
Step-by-step explanation:
4(x-3)=4x-12
So B or 4x-12 is correct.
