Answer:
a=3 and b=-2
Step-by-step explanation:
We are given that five terms of a quadratic sequence are
1 8, 21, 40, 65.
The nth term of this sequence
=
We have to find the value of a and b where a and b are integers.
For n=1
......(1)
For n=2
.....(2)
Subtract equation (1) from (2) we get
Using the value of a=3 in equation (1)
Hence, the value of
a=3 and b=-2
We know the sum of all the angles in a quadilateral is equal to 360. so,
it would be: 360 - (74+93+117)
= 360 - 284
= 76 degrees
So, Your final answer is 76 degrees.
Hope this helps!
Answer:
The answer is B
Step-by-step explanation:
i took the test and got it right on edge Give me brainiest please :)
12 ÷ 3 - 5(12) + 4(12 - 2)
= 4 - 60 + 4(10)
= -56 +40
= -16
Answer:
n=10
