The formula to find the interior angles is :
(n-2)×180°
Wheras n=the number of sides.
Angles sum of 25-gon therefore will be:
(25-2)×180°
=4140°
Thus,4140° is the answer.
Hope it helps!
It looks like you intend
x¹⁹ -2x¹⁸ +7x¹⁷ -12x¹⁶ +6x¹⁵ = 0
x¹⁵(x -1)²(x² +6) = 0
x = 0, 1, ±(√6)i . . . . . . . selection D is appropriate
You can remove the first plus sign to give:
-1.3 -4.9 [ because + x - = - ]
and by the same rule you can remove the the second plus sign to give
-1.3 -4.9 - 2.6
That means option b is out because it is positive.
straight away we can see that option D. equals the result, so it is in the running, so now can we eliminate c and a?
we can eliminate a because the minus ign outside the bracket multiplied by -4.9 inside the bracket produces + 4.9, which is not the answer, so that only leaves c.
once again, a plus sign outside the bracket does not produce -4.9 when muliplied by 4.9 inside the bracket inside option c, so we can eliminate option c.

Answer (D)
2/9=0.222
The answer would be 0.
Answer:
OMG IS THIS IXL my mom paid for me and my sister to use this I HATE IT!!!
Step-by-step explanation:
f(x)=mx
23(5)=m5
115=m5
m=23
slope is 23
i think this is what you needed. im sorry if this is wrong....
PLEASE MARK AS BRAINLIEST!!!! I WOULD REALLY APPRECIATE IT!
STAY SAFE BBY!
