The width of a rectangular piece of cloth is 4/5 meter. The area of the piece of cloth is 6 2/5 square meters. What is the length of the piece of cloth?

Length = 8

Step-by-step explanation:

If Area = L • W then if we have the area and the width we should divide the Area by the width to get the length.

6 2/5 divided by 4/5 = 8

Steps:

1) convert 6 2/5 to improper fraction and switch sign: 32/5 • 5/4 = 8

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
