Answer:
12%
Step-by-step explanation:
let x represent the actual number of members last year.
current members = 675 and with an increment of 13% over previous year
to find the increment
(675 - x) / x = 0.13
675 - x = 0.13x
collect the like terms
675 = 0.13x + x
675 = 1.13 x
x = approx 597 members were there last year
its hope to increase by the same number next year
percent increase = 675 - 597 / 675 = 78 / 675 = 0.12 = 12%

Answer:
-4
Step-by-step explanation:
From the qquadratic formula
x1 = [ -b +√(b² - 4ac) ] / 2a
x2 = [ -b -√(b² - 4ac) ] / 2a
When added together the ± square root cancels out leaving
(-b/2a) + (-b/2a) = -b/a
For 2x² + 8x -3 = 0
-b/a = -8/2
-b/a = -4
