Answer:
x=-11
Step-by-step explanation:
Distribution method
(2x+6)(2x-6)
=4x^2-12x+12x-36
=4x^2-36
The answer is: 30 skiers were participating in the ski trip.
Method:
$50S = $1,850 - $350 = $1,500
S = 1,500/50 = 30
Therefore, 30 skiers went on the trip
First, identify what fracion of an hour Larre spent outside using the model.
Since the square is divided in 4 equal parts, then the denominator of the fraction that Larre wants to represent is 4.
On the other hand, since 2 of those 4 parts are colored, then the numerator of the fraction that Larre wants to represent is 2.
Then, the fraction represented by the visual model is:

To find the answer, find an equivalent fraction by multiplying both the numerator and the denominator by 2:

Therefore, an equivalent fraction that can be made by multiplying the numerator and denominator by 2, is:

The correct choice is option C) 4/8.
