Answer:
3x-3
Step-by-step explanation:
You have to combine like terms. <em>x</em> and 2<em>x</em> have the same variable, so this equals 3x, and then you subtract 3 so:
x-3=2x-3-x
=3x-3
Answer:
b = 363
Step-by-step explanation:
Sum of a geometric Progression is expressed as attached.
a = 3 = the first term
r = 3 = the common ratio
n = 5 = number of term
Sum of GP = a(r^n - 1)/ r-1
= 3(3^5 - 1)/ 3-1
= 3(234 - 1) / 2
= 3(242) / 2
= 726/2
= 363
