im assuming the equation is:-
3 / (2g + 8) = (g + 2) / (g^2 - 16)
3(g^2 - 16) = (2g + 8)(g + 2)
3g^2 - 48 = 2g^2 + 4g + 8g + 16
Answer is A x = -4
3g^2 - 2g^2 - 12g - 64 = 0
g^2 - 12g - 64 = 0
( g + 4)(g - 16) = 0
g = - 4, 16.
Test these solutions:-
g = -4
left side = 3/0 which is indeterminate
right side = -2/0 indeterminate
So x = -4 is extraneous.
x = 16:- LHS = 0.075 RHS = 0.075 so x = 16 is a root.
Answer:
$128000
Step-by-step explanation:
Using the given formula :
I = P × R × T
I = 80000 × 15/100 × 4
I = $48000
He saves = 48000 +80000 = $128000
There are 6 coins that are each worth more than 5 cents. In total, there are 16 coins. So, the probability is 5/16.
Good luck!
