Answer:
d
Step-by-step explanation:
The equation of a line which passes through the origin is
y = mx ( where m is the slope )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = (1, 4)
m = = 4 , thus
y = 4x → d

Answer:
The answer to your question is length = 21.73 and width = 11.73
Step-by-step explanation:
Data
Total area = 255 ft²
length = x + 10
width = x
Formula
Area of a rectangle = length x width
Substitution
255 = (x + 10)(x)
Expand
255 = x² + 10x
Equal to zero
x² + 10x - 255 = 0
Solve with the quadratic formula
x =
x =
x =
x₁ = 11.73 x₂ = -21.73
There are no negative dimensions so the answer is 11.73.
Length = 11.73 + 10 = 21.73 ft
