Binomial (-2x – 8) and trinomial (-3x2 + 4x + 5) are the factors of which polynomial? A-3y2 + 2x - 3
O. B. -3x38x2.42x - 40
C 6x + 24x2.50% - 40
O. D 6x3 + 16x2 - 42x - 40

D

Step-by-step explanation:

-2x × -3x^2 +-2x ×4x +-2x×5 +-8×-3x^2 + -8×4x+ -8×5

6x^3-8x^2-10x+24x^2-32x-40

6x^3+16x^2-42x-40

(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
