Step-by-step explanation:

When given that function (f) is the following,

The wisest move to first make is to factor the expression, factoring is the process by which one rewrites a quadratic expression as the product of two linear expressions,

If is given that function (g) is the following,

Then one should also factor the expression,

One is asked to find the following,

To do this operation, one must multiply the two functions together. It is easiest to do so when the functions are in factored form,

Substitute,

Simplify, cross out like terms in the numerator and denominator,

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.

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:
