Question 4
Solve 4(3x + 5) = 2

-3/2

Step-by-step explanation:

So we have the equation:

Distribute the left:

Subtract 20 from both sides:

Divide both sides by 12:

So, our answer is -3/2 or -1.5.

And we're done!

588245.  

Step-by-step explanation:  

nth term = an = a1 r^(n-1)   where a1 = the first term  

a3 = 35 = a1  7^(3 - 1)  

35 = a1* 49  

a1 = 35/49 = 5/7  

So the 8th term = (5/7)* (7)^7

= 588245
