Choose the constant term that completes the perfect square trinomial. y^2 + 8y a. +16 b. -16 c. +64

A) +16

Step-by-step explanation:

y^2 + 8y + x

Let "x" be the constant term.

We have to find the factors of constant term such that when we add the factors we have to get 8.

4*4 = 16

When we add them, we get 7 + 4 = 8.

Therefore, the trinomial is y^2 + 8y + 16.

The answer is A) +16

Hope this will helpful.

Thank you.

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:
