Select the correct answer. Which expression represents a quadratic expression in complete factored form?
А.(2x + 4)(x+3)
B. (x - 2) + (x + 3)
C. (x + 4)(x – 3)
D. (x - 1)(3x – 9)

step-by-step explanation:

i think you should think about the question and not look online.

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees

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:

4
