60 12×5 is 60 all you really need to look at is the 12
2x+6 is the base
Then the equation is logarithm of 144 on basis 2x + 6 = 2
Then [2x + 6]^2 = 144
Now expand the square binomial
4x^2 + 24x + 36 = 144
4x^2 + 24x + 36 - 144 = 0
4x^2 + 24x - 108 = 0
Divide by 4
x^2 + 6x - 27 = 0
Factor: (x + 9 ) (x - 3) = 0
x = -9 and x = 3
The only valid is x = 3, because x = -9 yields 2x + 6 = - 12 and the logarithm function cannot have negative basis.
Then the answer is x = 3.

Answer:
60 pairs of shoes
Step-by-step explanation:
To find the answer, multiply 4x15. The words four times as many mean to do the operation of multiplication. 4x15= 60 So finally, each have 60 pairs of shoes.

Let us assume the total amount of money Joshua had = x
Amount of money Joshua had left after spending on souvenir = $16
Then
(3x/7) + 16 = x
3x + 112 = 7x
112 = 7x - 3x
112 = 4x
x = 112/4
= 28
Now
The amount of money spent on souvenir = (3/7) * 28
= 3 * 4 dollars
= 12 dollars
So the total amount of money spent on souvenirs by Joshua is $12
