Divide (-3x^2 - 9x) ÷ (x + 3)
please explain/show work! <33

Step-by-step explanation:

This is the original equation so you will open the brackets.

The x will cross the division sign making it times x.

So you will proceed to multiply the 9x by x making it;

So you will subtract 9x² from 3x² which won't be possible so it will be negative.

Then you will square root both sides making it;

So the ² will cancel the √ leaving

-6x=√3

-6x=1.73(Divide both sides by -6)

x=0.288

That's the final answer.

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is symmetric about the line y = 120,000.

step-by-step explanation:

(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
