Ricardo is factoring the polynomial, which has four terms. 5x3 + 20x2 + 2x + 8 5x2(x + 4) + 2(x + 4) which is the completely factored form of his polynomial?

The first step of factorization is done for you.  All that is needed to be done is a simplification of the factored polynomial.

5x^2(x+4)+2(x+4)

*Factor out an (x+4)*

(x+4)(5x^2+2)

Hope this helps!!

one that is bigger than 3 1/2

(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
