For p(x) = 4r? - 28x + 24, p(-3) = 0. Which of the following must therefore be true? A-3 is a factor of p(x) = 4r? - 28x +24.
B-3x is a factor of p(x) = 4x' - 28x + 24.
CX-3 is a factor of p(x) = 4r* – 28x + 24.
D x+3 is a factor of p(x) = 4x® – 28r + 24.

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.

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:

after 1 year: 221 deer

step-by-step explanation:

30% of 170 is 51. 170+51=221
