Answer:
area = 6m + 51 feet²
Step-by-step explanation:
area = length × width = 3(2m + 17) = 6m + 51
17 = 5k-2
+2 +2 The first step is to add 2 to both sides
-------------
19 = 5k Then you divide both sides by 5
The answer is 3.8 = k
The value of r in the given coordinates with their slope is; r = 7
How to find the Slope of a Line?
The formula for slope of a line passing through 2 points is;
m = (y2 - y1)/(x2 - x1)
We are given the coordinates as;
(1,-10) and (r,2)
The slope of the line passing through this coordinates is 2. Thus;
(2 + 10)/(r - 1) = 2
12 = 2r - 2
2r = 14
r = 14/2
r = 7
