Step 2: Put all x on one side Answer: Answer is x = 0.
Step-by-step explanation:
First take out all the parenthesis and this becomes your equation.
5x - 4 = -6x -4
The put all of the x on one side.
5x -4 + 6x = -4
Then put your constants on the other side
5x + 6x = -4 + 4
And now you add.
11 x = 0
For your last step you divide your constant by your variable which is 0/11x and thats how you get 0 :)
x = 0
Hope it will help the formula SOHCAHTOA means Sin=oppsite\hypotenuse Cos=adjacent\hypotenuse and Tan=opposite\adjacent
The temp. started at -20. If it rose +8 degrees, then it would be -20+8=-12, because since the -20 and +8 are opposites, you would subtract them and the answer would have the sign of the larger number which is -. so -12 is the answer.
Half-perimeter=length+width=width+3+width=43, 2×width=40 so width=20cm and length=23cm.
