Basically, you just have to distribute and then add. Let's do that:

30. 
x( \frac{3}{2}x-2)+6( \frac{5}{2}x- \frac{2}{3})
(\frac{3}{2}x^2-2x)+( \frac{15}{2}x -4)

Combine like terms (and this is your answer):
\frac{3}{2}x^2- \frac{11}{2}x - \frac{2}{3}

31. Same thing (except convert 1 and 1/5 to an improper fraction):
(\frac{6}{5})(x+ \frac{3}{2})- \frac{9}{10}
\frac{6}{5}x + \frac{9}{5} - \frac{9}{10}
\frac{6}{5}x +  \frac{9}{10}

Hope this helped!

Give a recursive formula for this sequence: 1,4,7,10,13,16....<br> PLEASE HELP ME! Tysm! (:
Valentin [98]

Answer:

a_{n+1} = a_{n} + 3 ; a₁ = 1

Step-by-step explanation:

Given

1, 4, 7, 10, 13, 16, ......

Note the difference in consecutive terms is constant, that is

4 - 1 = 7 - 4 = 10 - 7 = 13 - 10 = 16 - 13 = 3

Thus to obtain the next term in the sequence ( recursive formula )

Add 3 to the previous term

a_{n+1} = a_{n} + 3 ( with a₁ = 1 )
