I think it's because all the other colors are dark and the darker the color, the more heat it absorbs. yellow or white or basically light colors would reflect the light. this is just if it is talking in terms of temperature.
Answer:
f(x) = x² - 9
Step-by-step explanation:
Given x = a is a zero of the polynomial f(x) then (x - a) is a factor
Given zeros are x = 3 and x = - 3, then corresponding factors are
(x - 3) and (x - (- 3) ), that is
(x - 3) and (x + 3)
The function is then the product of the factors, that is
f(x) = (x - 3)(x + 3) ← expand using FOIL
f(x) = x² - 9
define the 3 numbers
smallest number = x
middle number = x + 2
largest number = x + 4
write the equation
sum of the smallest number and twice the middle number
20 more than the largest number
equal the expressions
the numbers should be 10, 12 and 14
Answer:
The answer should be "No Solution" as these lines never meet each other
It should be 15. 88 minus 28 is 60. Then 60 divided by 4 is 15.
