X=7

(x - 3 )(x +5)

(x+3) (x-5)

X - 35

Step-by-step explanation:

2x = 16 - 2

2x = 14

X= 7.

azamat

Answer:

$0.21

Step-by-step explanation:

We can set up a proportion. Say x is the cost of 1 wristband:

\frac{5.25}{25} =\frac{x}{1}

Now, we cross multiply:

25x = 5.25

Solving for x, we see that x = 0.21.

Thus, the answer is $0.21.
