Write and solve an equation for the situation. The perimeter of a parallelogram is 56 meters. The width of the parallelogram is 8 meters less than its length. Find the length and the width of the parallelogram.

The width is 10 meters and the length is 18 meters

Step-by-step explanation:

P = 2( l+w)

56 = 2(l+w)

w = l-8

Substitute for w in the perimeter equation

56 = 2( l+l-8)

Combine like terms

56 = 2 ( 2l-8)

Divide each side by 2

56/2 = 2/2( 2l-8)

28 = 2l-8

Add 8 to each side

28+8 = 2l-8+8

36 = 2l

Divide by 2

36/2 = 2l/2

18 = l

Now find w

w = l-8

w = 18-8

w = 10

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
