Answer:
1) 3x+18=45 x=9
2)8-5x=-7 x=3
3)3+2x=15 x=6
4) 12million - 2 million = 10 million
Step-by-step explanation:
3.14×20
20=diameter
=62.8cm
Let α be one of the zeros of the polynomial.
Other = 4α
α + 4α = - Coefficient of x / Coefficient of x² = -5/3
5α = -5/3
α = -5/3*5
α = -1/3
α * 4α = Constant term/Coefficient of x²
4α² = k / 3
