Hello,

Multiplying (x-1) by (4x+2) the term in x² is x*4x=4x².
If we substract 4x² the term of y in x² will be 0.
The function is not quadratic.

Since 4x*(-1)+2*x=-2x (product of terms in x) : the function is thus linear.

Constant term is -1*2=-2

Anestetic [448]

Answer:

-1 1/5

Step-by-step explanation:

<em>Change the whole number 4 to an improper fraction</em>

-4 4/5 ÷ 4/1 = -4 4/5 ÷ 4/1

<em>Reciprocal the 4/1 will become 1/4 then go to multiplication</em>

-4 4/5 ÷ 4/1 = -4 4/5 × 1/4

<em>Change to improper fraction the -4 4/5</em>

-4 4/5 ÷ 4/1 = -24/5 × 1/4

<em>Then simply multiply the two numerators and the two denominators</em>

-4 4/5 ÷ 4/1 = -24/20

<em>Finally, Simplify it to get the answer</em>

-4 4/5 ÷ 4/1 = -1 1/5

The length of a rectangle is 3ft more than twice the width, and the area of the rectangle is 54ft^2. Find the dimensions of the
777dan777 [17]

Answer: Let length = 2x + 3

Let width = x

Area = 54 ft2

length × width = Area

x(2x + 3) = 54

2x2 + 3x = 54

2x2 + 3x - 54 = 0

(2x - 9)(x + 6) = 0

x = 9/2 and x = -6

x = 4.5 and x = -6

We accept x = 4.5 because length cannot be a negative value. Substituting this value into the dimensions:

width = 4.5 ft

length = 2(4.5) + 3 = 9 + 3 = 12 ft

Step-by-step explanation:
