A rectangle has a length of 2x+7 and a width of 3x+8. Write and simplify an expression for the perimeter of that rectangle.

What is the answer to this?

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

10

step-by-step explanation:

7+3=10

here is a big fat

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:
