C. square
2. Which polygon is always irregular?
traingle - NOT (equilateral triangle)
trapezoid - YES
square - NOT
hexagon - NOT (regular hexagon)
D^2 - 4d = 3d
d^2 - 7d = 0
d(d - 7) = 0
d = 0 or d - 7 = 0
d = 0 or d = 7
Answer:
evaluate the function with -3 as x value
Step-by-step explanation:
4(-3) + 5
-12 + 5
= -7
6 √3. Short leg is half the hypotenuse is 6 so x = long leg so x= short leg times √3
