Answer:
10
Step-by-step explanation:
(f + g)(x) = f (x) + g(x)
(f + g)(2) = f (2) + g(2)
= (-4) x 2 + (3 x 2 + 12)
= -8 + 18 = 10
Well where can I see what x would be I only have the answers?? I need the actual problem

LCM=180/3=60
Answer:
The circumference is 66cm
Radius = Diameter/2
= 21/2 CM
= 10.5 CM
Circumference of a circle = 2πr
= 2 × 22/7 × 10.5 CM
Answer:
r = 11 units
Step-by-step explanation:
Given that,
The measure of Arc CD is 11x
The arc is making an angle of 180°.
We know that,
Length of the arc,
Where
r is the radius of the circle
So,
So, the radius of the circle is equal to 11 units.
