How many solutions exist for the given equation? 0.75(x + 40) = 0.35(x + 20) + 0.35(x + 20)
2 answers:
Answer:
One solution
Step-by-step explanation:
The given equation is;
0.75(x + 40) = 0.35(x + 20) + 0.35(x + 20)
Multiply through by 100
75(x + 40) = 35(x + 20) + 35(x + 20)
Combine the right hand side
75(x + 40) = 70(x + 20)
Expand the parenthesis
75x +3000 = 70x + 1400
Group similar terms;
75x -70x =1400-3000
5x=-1600
Divide both sides by 5
x=-320

3x^2−4x−4
Step-by-step explanation:
3x^2−8x−2+4x−2
=3x^2+−8x+−2+4x+−2
3x^2+−8x+−2+4x+−2
=(3x^2)+(−8x+4x)+(−2+−2)
=3x^2+−4x+−4
