Answer:
23
Step-by-step explanation:
P E M D A S
8+6÷2+(2+10)
P)
8+6÷2+(2+10)
8+6÷2+(12)
E)
M)
D)
8+6÷2+(12)
8+3+12
A)
8+3+12
11+12
S)
The final answer is 23.
The total bill would be 67.32 because you have to multiply the tax and tip then add them together
Given x ^2 −3x+2=0
x ^2 −2x−1x+2=0
(Resolving the expression)
x(x−2)−1(x−2)=0 (Taking common factors)
(x−2)(x−1)=0 (Taking common factors)
∴x−2=0 or x−1=0 (Equating each factor to zero)
∴x=2 or x=1
∴2 and 1 are the roots of x ^2 −3x+2=0

Answer:
B
Step-by-step explanation:
In this graph we can see a "Parabola", this is the curve for a second degree polynomial function, and based on "Fundamental theorem of algebra" we can know that this polynomial has 2 roots (they can be real or imaginary).
In this graph, the curve doesn't touch the X axis, so we know that this function has not real root. So both roots are complex
