Which method would be best to use to factor the polynomial 2x7 – 4x6 – 70x5?

Step-by-step explanation:

To factor the given expression, factor out GCF

GCF is 2x^5

So factor out GCF from the given expression

Now factor x^2-2x-35

Product is -35 and sum is -2

-7 times 5 is -35

-7+5=-2

So factors are -7 and 5

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

(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
