A 40 inch wire is to be cut. One piece is to be bent into the shape of a square, Where is the other pieces to be bent into the shape of a rectangle whose length is twice the width. Find the width of the rectangle that will minimize the total area

I think it would be 4 because 32+8=40 and has a area of just 64

Step-by-step explanation:

answer

the correct answer is

explanation

the given function is

the excluded values are obtained by solving:

we factor to obtain:

the excluded values are

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
