The sum of the first five terms is 11/2
<h3>How to determine the sum?</h3>
The series is given as:
1/2, -1,2,-4…
Calculate the common ratio of the series using
r = -4/2
Evaluate
r = -2
The sum is then calculated as:

This gives

Evaluate

Evaluate

Hence, the sum of the first five terms is 11/2

Answer:
x=12
Step-by-step explanation:
32/2x = x/9; because the triangles are similar
32 = 2x^2/9
288 = 2x^2
144 = x^2
x = 12 or x = -12, but the latter is nonsensical.
Least: 8 (length) x 1(width) = 8
Greatest: 5 (length x 4 (width) = 20
The difference between them: 20 - 8 = 12<span />
we have
------> inequality A
The solution of the inequality A is the shaded area below the solid red line
see the attached figure N
------> inequality B
The solution of the inequality B is the shaded area above the dotted blue line
see the attached figure N
therefore
The solution of the system of inequalities is the shaded area between the solid red line and the dotted blue line
see the attached figure N
therefore
the answer in the attached figure N
