Answer:
Step 3 they took the square root incorrectly
Step-by-step explanation:
5 ( x-2)^2 +6 = 86
Subtract 6 from each side
5 ( x-2)^2 +6 -6= 86-6
5 ( x-2)^2 = 80
Divide each side by 5
5 ( x-2)^2 /5 = 80/5
(x-2)^2 = 16
Take the square root of each side
sqrt((x-2)^2) = ±sqrt(16)
x-2 = ±4

Answer:
Brand X has to mix 8.4 oz of brand A mixed nuts which contain 35% peanuts and 12.6 oz of brand B mixed nuts which contain 25%, to obtain 21 oz. Bags of mixed nuts that contain 29% peanuts.
Step-by-step explanation:
Hi
We define
, wich means Brand A has 1 oz containing 35% peanuts.
, wich means Brand b has 1 oz containing 25% peanuts.
So we can build an equiation system
(1) 
(2)
, after fixing it a little
(2)
As we can use any method to solve the system, I used a calculator wich thrown the following results 
and 
.
Answer:
x=2
Step-by-step explanation:
6^x^10 = 6^12^2 / 6^4
We know a^b^c = a^(b*c)
6^ 10x = 6^(12*2) / 6^4
6^ 10x = 6^(24) / 6^4
We know a^b / a^c = a^(b-c)
6^ 10x = 6^(24 -4)
6^ 10x = 6^(20)
Since the bases are the same, the exponents are the same
10x = 20
Divide each side by 10
10x/10 = 20/10
x=2
