I need you to answer this question really fast and be 100% accurate!!!

Let...

length = x

width = y

We can make two equations from the information.

2x + 2y = 32 > x = 16-y

xy=60

Substitute "16-y" for x in the second equation and...

(16-y)y = 60

16y-y² = 60

y²-16y+60=0

(y-10)(y-6)=0

y=10,6

Width can be 6 or 10 ft and length as well so the dimensions are...

6 feet by 10 feet

Hope u find this helpful.

2 is the final ! : )

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:
