The length of a rectangle multiplied by 3 is equal to 4 times its width. The perimeter is 8 2/5 feet ( 8 wholes and 2/5 feet ) . Find the length and width.

hi,

3. 12.15, you are correct.

4.2.01, your first digit is correct,

hope this !

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x

unlimited solutions.

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:
