Answer: A. 62 m
<u>Step-by-step explanation:</u>
Perimeter is the sum of all of the sides
Top = 20
Sides = 2(8) = 16
<u>Bottom = 20 + 2(3) = 26</u>
Total = 62
Possible values of x and y for two distinct points (5, -2) and (x ,y) to represent a function is x ∈ R , x≠ 5 and y ∈ R.
As given,
Two distinct points to represent function are (5, -2) and (x. y )
Possible value of x and y to represent a function.
x represent domain
y represent range.
Each value of x (domain) mapped to y-value(range).
x can not be equal to 5 .
x and y take all real values except x≠5.
Therefore, possible values of x and y for two distinct points (5, -2) and (x ,y) to represent a function is x ∈ R , x≠ 5 and y ∈ R.

The answer is A. all three of the latitudes lie entirely outside the triangle
its a because all the altitudes have to cross each other so when an obtuse angle is being measured the altitudes have to cross but the only way they can can cross is if they are outside of the angle to get the right mesaurement
The function is:
f ( x ) = x² - x - 72
This is a quatdratic function. So we can find the zeroes of the function with the formula:
x 1/2 = ( - b +/- √(b² - 4 ac) ) / ( 2a )
And we have: a = 1, b = - 1 and c = - 72
x 1/2 = ( 1 +/- √((-1)² - 4 · 1· ( - 72 )) ) / 2
x 1/2 = ( 1 +/- √( 1 + 288 ) ) / 2
x 1/2 = ( 1 +/- √289 ) / 2
x 1/2 = ( 1 +/- 17 ) / 2
x 1 = ( 1 - 17 ) 2 = - 16 / 2 = - 8
x 2 = ( 1 + 17 ) / 2 = 18 / 2 = 9
Answer: The zeroes are - 8 and 9.
