Answer:
11, 25
Step-by-step explanation:
n is a number
2n + 3 is the other number
n + 2n + 3 = 36
Answer:
3 - 3i
Step-by-step explanation:
I think you meant:
6
------------
1 + i
To simplify this, that is, to "rationalize the denominator," multiply both numerator and denominator by the conjugate of 1 + i, which is 1 - I:
6(1 - i)
----------- = 3(1 - i)= 3 - 3i
1 -(-1)
We have to divide both sides by -4 to get x by itself and solve the inequality
-4x∠16
---- ---
-4 -4
x∠-4
thats your final answer

Answer: 1260 degrees</h3>
Explanation:
There are n = 9 sides to this polygon. Plug this value of n into the formula below to find the sum of the interior angles.
S = 180(n-2)
S = 180(9-2)
S = 180*7
S = 1260
Answer:
- a) f(x) = - 20x + 450
- b) 30 pages left to read
Step-by-step explanation:
<u>Given sequence:</u>
The first term is 430 and the common difference is - 20.
a)
<u>Required function is:</u>
- f(x) = 430 - 20Ix - 1) = 430 - 20x + 20 = 450 - 20x
or
b)
<u>Find the number of pages left after 21 days:</u>
- f(21) = 450 - 20*21 = 450 - 420 = 30
