Let each side perpendicular to the wall be x
The parallel to the wall will be 320-2x
the area will be:
A(x)=x(320-2x)
A(x)=320x-2x^2
This is a quadratic with a =-2 and b=320
Maximum area will occur where x=-b/2a
=-320/(-2*2)
=80 ft
thus the width will be 80 ft and the length will be:
length=320-2*80=160 ft
Answer:
A
Step-by-step explanation:
On a graph, find the point of intersection of two lines; the first line has y-intercept = 5 and slope = −3, and the second line has y-intercept = 2 and slope = 1. Option A is correct.
Given that,
y = −3x + 5 ,
y = x + 2
Which of the following statements best explains the steps to solve the pair of equations graphically is to be determined.
<h3>What is the equation?</h3>
The equation is the relationship between variables and is represented as y = mx + c is an example of a polynomial equation.
Here,
Intersection point of two lines on the graph is system of solution for the pair of the equation,
Thus, On a graph, find the point of intersection of two lines; the first line has y-intercept = 5 and slope = −3, and the second line has y-intercept = 2 and slope = 1. Option A is correct.

The Greates Common Factor (GCF) is: 1
Answer:
n = - 10
Step-by-step explanation:
10(-3n + 8) = 380
-30n + 80 = 380
80 - 380 = 30n
30n = - 300
n = - 300 : 30
n = - 10
