Answer:
Step-by-step explanation: Sub -3 into where all the u’s are. So it would be
(-3)^2 - 2(-3) + 4
Which would equal 19
How many times does (4) go into (37) ? 9 TIMES.
Remainder 1.
So as a mixed number would be 9 whole number, 1/4
= (9 1/4)
Answer:
(7x-3)/-1
Step-by-step explanation:
swap the x and y and then move the y by itself
x=(3-y)/7
7x=3-y
7x-3=-y
(7x-3)/-1=y
Answer:
8xº = 90º
6xº = 67.5º
2xº = 22.5º
x = 11.25°
Step-by-step explanation:
The sum of angles in a triangle is 180°
8xº + 6xº + 2xº = 180º
16xº = 180º
x = 11.25º
8xº = 11.25(8) = 90º
6xº = 67.5º
2xº = 22.5º
Hope this helps :)
OCTA=8, an octagon has 8 sides, thus if one side is 6mm, then all sides, namely the perimeter, is 6+6+6+6+6+6+6+6, or 48.
now, we know what the apothem is.
