polynomial expression- ( 4x^4 + 3x^2 -1 ) + ( mx^3 + 2 ) ( 3x^2 + 1 ) is simplified to 15x^5 + 4x^4 + 5x^3 + 9x^2 + 1 . what is the value of m

7. d. 64

8. i. 32

9. c. 125

10. j. none of the above

11. d. 81

12. i. 216

13. e. none of the above

14. g. 240

15. e. none of the above

16. g. 32

17.   e. none of the above

(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

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
