Multiply it out
x^2 + 4x -8x -32
Combine like terms
x^2 -4x - 32
Evaluating the given sequence, it is evident that the next number is twice the number prior to it. Thus, the given is a geometric sequence with first term (a1) equal to 1 and common ratio of 2. The geometric series may be calculated by the equation,
Sn = a1 x (1 - r^n) / (1 - r)
where Sn is the sum of n terms in this case, n = 11.
Substituting the known values,
<span> Sn = 1 x (1 - 2^11) / (1 - 2) = 2047
</span>
Thus, S11 is 2047.
Answer:
50
Step-by-step explanation:
its a straight line so all the angles have to add up to 180
2.45 is smaller.and thats it
Answer:
Subtract c, then divide by m.
