Answer:
Step-by-step explanation:
Let w be the width
Length = 3w +15
Perimeter = 94 cm
2*(length + width) = 94
2*(3w+15 + w) = 94
2*( 4w + 15) = 94
4w + 15 = 94/2
4w +15 = 47
4w = 47 -15
4w = 32
w = 32/4
w = 8 cm
Length = 3w +15 = 3*8 + 15 = 24 +15 = 39
Length = 39cm
Area = length * width = 39*8 = 312
Area = 312 cm²
Answer:

Step-by-step explanation:
The constant of direction variation givens a proportion that is maintained by both x and y values for all points of a line that it passes through.
Usually represented with the variable
, it is given by:
for coordinates (x, y).
This relationship can be written as
which is also the layout for a proportional relationship.
Since coordinates are written (x, y), for point (5, 8), substitute
to get the constant of variation:
