Simplify the expression 4(2x-1)-3(x+5)

The answer is

Step-by-step explanation:

4(2x-1) - 3(x+5)

Expand the terms in the bracket

That's

8x - 4 - 3x - 15

Group like terms

We have

8x - 3x - 4 - 15

We have the final answer as

Hope this helps you

(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
