Answer:
x=-3 x=-1 x=2 x=-2
Step-by-step explanation:
p(x) = (x^2 + 4x + 3)(x^2 – 4)
Set this equal to zero to find the x intercepts
0 = (x^2 + 4x + 3)(x^2 – 4)
Using the zero product property
(x^2 + 4x + 3) =0 (x^2 – 4) =0
Factor
(x+3)(x+1) =0 (x-2) (x+2)=0
Using the zero product property
x+3 =0 x+1 =0 x-2 =0 x+2 =0
x=-3 x=-1 x=2 x=-2
The slope intercept form is y = mx + c.
The quantity given by the constant term c, is the vertical or y intercept.
It is the point where the line cuts the y axis, and this point, x = 0.
Cosine law
a²=b²+c²-2ab*cosA
a²=13²+11²-2*13*11*cos(108)≈378.37
a≈19.45
Answer:
D
Step-by-step explanation:
Combine the fractions by finding a common denominator (A denominator shared by two or more fractions.)
Answer:
