Simplify.
(x^2 + 5^x + 8)(x^2 + 2^x + 6)

a. x4 + 10x2 + 48
b. x4 + 2x3 + 6x2 + 7x + 14
c. 2x2 + 7x + 14
d. x4 + 7x3 + 24x2 + 46x + 48
can you also explain?

(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

is this part of a question or something
