Answer:
15m
Step-by-step explanation:
Since the square has an area of 9m^2 it has to have sides that are 3m. There are 3 sides that are 3m. An equilateral triangle has the same sides so it has 2 sides that are 3m. There are 5 sides that are 3m. The perimeter is 15m.
First, the range is all about the y-values, so the set notation needs to have the form:
{ y : y __________}
Because of that, you can eliminate the first and third options that use “x”. Using x would reference the domain.
Second, the range is the set of all y-values used in the function. You only include y-values in the range, so you’d only include 8, 3, -2, and -7 in your answer.
That means it’s the second answer.
Side note:
Some areas would use the notation { y | y = -7, -2, 3, 8}, using “|” instead of “:” in the set notation.f
Y=5^x when x is 2.
y=5^2
y=25
Hope this helps!
