If (X + 8) is a factor of f(x), which of the following must be true?

•Both x = -8 and x = 8 are roots of f(x).
•Neither x = -8 nor x = 8 is a root of f(x).
•f(-3) = 0
•f(8) = 0

B

Step-by-step explanation:

B, neither x = -8 nor x = 8 is a root of f(x).

1e+27

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
