Answer:

B is the only answer

Step-by-step explanation:

all other answers plug the amount of money (c) onto the whole amount that they've made, multplying in this manner would give a bigger number. B is the only excusable equation since plugging the (c) onto the West school would bring the total closer to the final amount.

What are the potential solutions of log4x+log4(x+6)=2

ivann1987 [24]

Answer:
x = 2 and x = -8

Explanation:
Before we begin, remember that:
log (x) + log (y) = log (xy)
log x² = 2 log x
log₄ (4) = 1

Now, let's see the question we have:
For the left hand side:
log₄ x + log₄ (x+6) = log₄ x(x+6)
For the right hand side:
2 can be rewritten as:
log₄ (4)²

Now, equating the left hand side with the right hand side:
log₄ x(x+6) = log₄ (4)²
We can deduce that:
x (x+6) = (4)²

We will now solve for x as follows:
x (x+6) = (4)²
x² + 6x = 16
x² + 6x - 16 = 0
(x-2)(x+8) = 0
either x-2 = 0 ...........> x=2
or x+8 = 0 ..............> x = -8

Note: The negative solution is usually rejected as no log can hold a negative value. However, since it is not eliminated in the given choices, we will consider it as a potential solution

Hope this helps :)
