lets draw a picture of our hexagon:
then, we can rotate 60 degrees counterclockwise (or clockwise) and get the same hexagon. So, the answer is 60 degrees
Y = x^2 - 8x + 5 Put brackets around the first two terms.
y = (x^2 - 8x ) + 5 Add (8/2)^2 on the inside of the brackets. Translated into mathese that means take 1/2 of the linear term (8x), drop the x and square the rest
.
(1/2 8)^2 = 4^2 = 16
y = (x^2 - 8x + 16) - 5 What you put inside the brackets, you must subtract outside the brackets.
y = (x^2 - 8x + 16) - 5 - 16 Combine like terms.
y = (x^2 - 8x + 16) - 21 Show what is inside the brackets as a square.
y = (x - 4)^2 - 21 <<<<<<<<< Answer.
Answer:
the triangle was rotated about 90 degrees i think
The LCM, (Least Common Multiple) of 12 and 30 is 60. You get this because 60 is the lowest number 12 and 30 both go in to.
Answers:
scalene (column 1)
right triangle (column 2)
==============================================
Explanation:
The lack of tickmarks tells us indirectly that none of the sides are equal to one another. So all three sides are different lengths. Therefore, the triangle is scalene. This rules out "equilateral" and "isosceles".
The small square marker indicates we have right angle, aka 90 degree angle. In turn, it leads to the fact we have a right triangle. This rules out "acute" because acute triangles have all three angles smaller than 90. We can also rule out "obtuse" because obtuse triangles have one angle larger than 90.
In short, this triangle is both scalene and a right triangle. We can call it a right scalene triangle, or a right triangle that is scalene.
