Width = W
Length = 2 times the width plus 3 feet = 2W + 3
Area of triangle A = L * W
A = W (2W + 3)
20 = 2W^2 + 3W
2W^2 + 3W - 20 = 0
(W + 4) (2W - 5) = 0
W + 4 = 0; W = - 4 (width cannot be negative, excluded)
2W - 5 = 0
2W = 5
W = 2.5
L = 2W + 3 = 2(2.5) + 3 = 8
Answer:
Width = 2.5 feet and Length = 8 feet
Hope it helps.
I think it is 128 but not 100%
X= -1
Use trial and error method
When you substitute x=-1 you will get 0 as the answer..!
Enjoy your day
Answer:
it increased 30.36%
Step-by-step explanation
100/56=1.785714286
1.785714286x73=130.35714286
130.35714286-100=30.35714286
30.35714286=30.36%
Part A: The y-intercept of the line of best fit is about 4. This represents the starting point, or figure 0.
Part B: Using the line, you could determine that the slope is about 3/2, or 1.5, and the 13th month would be at about 24 matches.
Equation: y=4x+1.5
Hope this helps,
