Answer:
the answer is a+b
Step-by-step explanation:
7(3a-2b) +5(3b-4a)
21a-14b+15b-20a
a+b
4 hours = 50$
6 hours = 75$
10 hours = 125$
50 + 75 + 125 = 250?
I'm not sure if I understood your question, because you didn't say like "What is all of these times together?"
The inside perimeter would be the perimeter of the garden: 17 + 17 + 20 + 20 = 74 feet.
The outside dimensions would be 6 feet longer on each side ( 3 feet wide on both sides for the sidewalk)
Outside perimeter: 23 + 23 + 26 + 26 = 98 feet.
Total = 74 + 98 = 172 feet.
Since the "x" points are equal, the line between the points is vertical.
So, basically, the distance between y = 1 and y = 4 is y = 3.
The point is located at (2, 3)
ANSWER
Focus:

Directrix:

EXPLANATION
The given parabola has equation:

We compare this to the general equation,

Comparing the coefficient of x, we have:
-4p=-1

The focus is (-p,0)

The equation of the directrix is
x=p
