Answer:
54
Step-by-step explanation:
Given:

Input the numbers provided into the equation
3(2 + 3 + 4)2
Add all of the numbers inside the parentheses
3(9)2
Multiply
3 * 2 = 6
6 * 9 = 54
Answer:

Step-by-step explanation:
The points on the straight line are (P, 0) and (0, R).
The slope would be

And
, because the y-intercept is at (0, R).
So, the equation of this line would be

Where we multiply the equation by 

Therefore, the equation that represents this line is

<h2>
So, the right answer is B.</h2>
Answer: y=-2x+6
Step-by-step explanation:

So
. We can substitute (0, 6) to get:
6 = 2(0)+b
b=6.
Meaning y=-2x+6.
