Answer:
Grade≥69(at least 69)
Step-by-step explanation:
(77+69+65+x)/4=70
x=69
so he must get 69 or more
Answer:
=x+2
Step-by-step explanation:
2(x+2)−(x+2)
Distribute the Negative Sign:
=2(x+2)+−1(x+2)
=2(x+2)+−1x+(−1)(2)
=2(x+2)+−x+−2
Distribute:
=(2)(x)+(2)(2)+−x+−2
=2x+4+−x+−2
Combine Like Terms:
=2x+4+−x+−2
=(2x+−x)+(4+−2)
=x+2
Answer:
=x+2
Answer:
(2, -7)
Step-by-step explanation:
The image is the point after the transformation. So basically we want to move backwards. the transformation is (x-6, y+8) so that means we want to find when we go in reverse, or in other words (x+6, y-8) from the image (-4, 1)
(x+6, y-8)
(-4+6, 1-8)
(2, -7)
You can check by transforming this point witht he transformation properly. And just a reminder (x-6, y+8) mans left 6 and up 8
1/2 of the side length p= 1/2 x 4 =2
centre angle=360/6=60 degrees
The APOTHEM bisects or divides the centre angle into two equal angles
1/2 of the centre angle=60/2=30 degrees
tan 30 degrees = 2/APOTHEM
APOTHEM=2/tan 30= 3.46 cm
The APOTHEM is the perpendicular height of the equilateral triangle given in the diagram.
Area of the equilateral triangle
=1/2 x 4 x 3.46
=6.93 cm^2
Area of the regular hexagon= 6 x area of the equilateral triangle= 6 x 6.93 =41.6 cm^2
Hope this helps!
