Subtract the second expression from the first. (4x^2 - 2x + 8) - (x^2 + 3x - 2) a. 3x^2 + x + 6 b. 3x^2 + x + 10 c. 3x^2 - 5x + 6 d. 3x^2 - 5x + 10

(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

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared
