Answer:
12 inches
Step-by-step explanation:
if it is a square then you do 3×4 to get the perimeter
Answer:
(2,-9)
Step-by-step explanation:
Multiply out the polynomial to get:
x^2-4x-5
the vertex formula is -b/2a (use the coefficients of the equation above)
-(-4)/2(1) = 4/2 = 2
we know the x value of the vertex is 2. Now we can plug that into the original equation to get the y value.
(2-5)(2+1)
(-3)(3) = -9
so the coordinate is (2,-9)
Answer:
It's B, 62.
First, you identify the median, (30,) and use this to identify the first and third quartiles. 2-18 are the first ranges, and 42-81 are the third.
You would need to split the ranges between the first quartile (9) and the third quartile (71).
The interquartile range is the difference between the first and third ranges, making it 62.
