Answer:
x^2 -2x = 4x+1
2x^2 +12x = 0
9x^2 +6x -3=0
Step-by-step explanation:
A quadratic equation has the highest power of x being squared
x^2 -2x = 4x+1
2x^2 +12x = 0
9x^2 +6x -3=0
These are all quadratic equations
Answer:
x = -3
Step-by-step explanation:
3(4x + 8) = - 35+23
Combine like terms
3(4x + 8) =-12
Divide by 3
3/3(4x + 8) = -12/3
4x+8 = -4
Subtract 8 from each side
4x+8-8 = -4-8
4x = -12
Divide by 4
4x/4 = -12/4
x = -3
Change 0.7 to 7/10 and 4 to 1/4,so it'll be 7/10x1/4, then find least common denominator, 40.change fractions to 28/40x10/40=280/40=70
