11. Complete the square for the expression x? - 14x + ?. What is the result when the completed trinomial is factored into a binomial squared?
a. (x + 7)
c. (x + 14)
b. (x - 14)
d. (x-7)

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45

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:

b

step-by-step explanation:

i think the answer is 90 hope this
