The quadratic equation has two solutions if b^2 - 4ac > 0
Given the equation ax^4 + bx^2 + c=0
Substitute into the formula to have:
The equation becomes aP^2 + bP + c = 0
For us to have a unique solution, the discriminant b^2 - 4ac must be greater than zero. Hence the quadratic equation has two solutions if b^2 - 4ac > 0

Answer:
3) 12 yd^2
4) 27.5 m^2
5) 48 ft^2
6) 96 m^2
Step-by-step explanation:
3) 4(2x3x0.5) = 12 yd^2
4) (9x5)-(0.5)(7x5) = 27.5 m^2
5) (10x6)-(6x2) = 48 ft^2
6) 12x8 = 96 m^2
F(x)=8x+2
f(6)=8(6)+2
f(6)=48+2

The total cost for this item is $18.19.
To find the sales tax of something, you move the decimal two places to the left on the percent. Then you multiply the items cost and the tax together, which gets you $1.19. Add the original amount with 1.19 and you get 18.19.
