Answer: No solution
Step-by-step explanation:
1. Expand the brackets- 9-3x+5x=2x+4
2. Add common terms- 9+2x=2x+4
3. Subtract 2x from both sides- 9=4
4. Nine cannot equal four and therefore, there is no solution.
To annoy everyone and make life hard as heck. There is no true purpose behind it and teachers just like to make everyone's home life 10x more annoying. They also do it because 99% of teacher are crazy cat people with no life. So for them homework keeps them busy
Y = 2x³, when x = -3
<span>y = 2*(-3)³
</span>
<span>y = 2*-27
</span>
y = -54
I think you can solve it by
=(x^2 - y^2) *( x^2 + y^2)
= (x -y)*(x+y)*(x^2 + y^2)
