Answer:
C
Explanation:
The place where the lines intersect is between the lines of the graph.
Let the length be x and the width be w
The perimeter will be:
2x+3w=1500
thus
3w=(1500-2x)
w=(1500-2x)/3
w=500-2/3x
The area will be:
A=x*w
A=x(500-2/3x)
A=500x-(2/3)x²
The above is a quadratic equation; thus finding the axis of symmetry we will evaluate for the value of x that will give us maximum area.
Axis of symmetry:
x=-b/(2a)
from our equation:
a=(-2/3) and b=500
thus
x=-500/[2(-2/3)]
x=375
the length will be 375 m
The width will be 250 m
Answer:
x/6 + 5 = 7
x/6 = 2
x = 12
Step-by-step explanation:
12 divided by 3 equals 4. And the. Parentheses means multiply, so 4x4=16
