The first way i.e. the 4(x)
Step-by-step explanation:
Its because there's no gap in between and the letter is surrounded by brackets on both sides so it cant be divided and it's the only letter . There's no rule in mathematics that allows you to multiply a single number surrounded by brackets at both sides.
How is she starting off with five yards of fabric but is using 13 and 72 yards of fabric something isn’t right with this question...
Let us assume rent for a child = $x per hour and
Rent for an adult = $ y per hour.
We are given number of children = 3.
Number of adults = 1.
Rent for 3 children at the rate $x per hour = 3*x = 3x.
Rent for 1 adult at the rate $y per hour = 1*y = y.
We are given number of hours of rafting trip = h hours.
Total cost of 3 children and 1 adult for h hours =h times (Cost of 3 children and 1 adult for each hour).
= h*(3x+y).
Therefore, h(3x+y) is the final expression for the total cost of h hours of rafting trip.
If you are given values of x, y or h, you can plug those values in this expression.

When there is only points and no lines, to find domain, you give the x values only, and to find the range you give the y values only.
When there is a line, for domain you go from left to right, and for range you go from bottom to top. The arrow indicates that the line is continuous, and so the second values for domain and range are infinity because we do not know the value.
