Answer:

Length = 7 ft and width = 4 ft

Step-by-step explanation:

It is given that, the area of a rectangular carpet is 28 square feet. The length is three feet more then the width.

<u>To find the length and width</u>

Let x be the width the length = x + 3

Area  of carpet = Length * Width

28 = (x + 3) * x

x² + 3x - 28 = 0

x² + 7x - 4x - 28 = 0

x(x + 7) -4(x + 7) = 0

(x + 7)(x - 4) = 0

x = -7 or x = 4

Therefore width = 4 ft then length = 4 + 3 = 7 ft

What are the real and imaginary parts of the complex number?
Licemer1 [7]

Answer:

The real part is 2

The imaginary part is -5

Step-by-step explanation:

A complex number consists of a real part and an imaginary part. For example given the complex number z = x+it

x is the real part of the complex number z i.e Re(z) = x

Imaginary part of the complex number z is y i.e Im(z) = y.

Note that the real part are on the x axis of a graph while the y axis is the imaginary axis attached to the complex notation i

Given the complex number 2-5i

Comparing 2-5i to x+iy

x= 2 and y = -5

The real part is 2 (value that is not attached to the complex notation)

The imaginary part is 5(value attached to the complex notation)

How do you solve this step by step
Afina-wow [57]
Display board measurements = 10ft by 6ft
So all the sides would be 10ft, 10ft, 6ft, 6ft
Add them all together= 32ft
Ribbon length would need to be 32ft long
