Answer:
441
Step-by-step explanation:
x^2 + 42x + c
Take the coefficient of x
42
Divide by 2
42/2 = 21
Square it
21^2 =441
This is the value of c
the sum of the interior angles in an ngon is (n-2)*180
so if the sum of the interior angles is 2880, then
2880=(n-2)*180
solve for n
divide both sides by 180
14=n-2
add 2 to both sides
16=n
n=16
Answer:
B) 2a√15a
Step-by-step explanation:
Simplify the radical by breaking the radicand up into a product of known factors, assuming positive real numbers. 2a√15a
