Answer:
(-4,0) and (4,0)
Step-by-step explanation:
The x-intercepts occur for values of x where f(x) = 0.
f(x) = 0 when the nominator () = 0.
is a difference of squares,
so you can factor it as (x + 4)(x – 4)
When x = –4 or x = 4, the nominator is 0, and f(x) = 0
Answer:
The relationship exists, so this is a perfect square trinomial.

Step-by-step explanation:
A= 320 cm2 and that is the answer
A perfectly straight line is 180°, and the right side of the angle of the line is 60°, so the left angle must be 180°-60°, which is 120°
Answer:
x=10
Step-by-step explanation:
set it up and solve
2x-1=x+9
2x=x+10
x=10
