Because triangle ABC is equilateral, FC is 9
Let's first define the variables:
x = width
300 - 2x = long
The area will be:
A = (x) * (300 - 2x)
A = 300x - 2x²
We look for the maximum area, for this, we derive:
A '= 300 - 4x
We match zero:
0 = 300 - 4x
x = 300/4 = 75
Therefore, the width is:
x = 75 feet
The length is:
300 - 2x = 300 - 2 (75) = 300-150
150 feet
Answer:
Part A:
The maximum area will be:
A = (150) * (75) = 11250 square feet
Part B:
The dimensions are:
Length = 150 feet
width = 75 feet
Answer: 426
Step-by-step explanation:
221 - 33 = 288
288 - 4 = 284
284 / 2 = 142
284 + 142 = 426
Y=2/3x-1 is the equation:)
What you do is multiply x and y by 4 so the new be point is (-36,24)
