(2+3i)+2i(2+3i) = 1(2+3i) + 2i(2+3i) = (1+2i)(2+3i)
With geometric sequences, all you have to do is multiply each term by -3 until you get to the needed term.
First term: 2
Second term: 2 * -3 = -6
Third term: -6 * -3 = 18
Fourth term: 18 * -3 = -54
Fifth term: -54 * -3 = 162
The fifth term of the sequence is 162.
Hope this helped, please consider making me brainliest!
Answer:
If the factors are ALL binomials, then the number of factors is the degree of the polynomial. If some of the factors have been left as quadratics (because there are complex roots), the count 2 for each quadratic and 1 for each binomial, the sum is the degree.
A square rotated about its center by 360º maps onto itself at 4 different angles of rotation. You can reflect a square onto itself across 4 different lines of reflection.
100%/x%=61/152.5
(100/x)*x=(61/152.5)*x <-- - we multiply both sides of the equation by x
100=0.4*x <-----we divide both sides of the equation by (0.4) to get x
100/0.4=x
250=x
x=250
250%=final answer
