6.7 10 squared positive 8
I feel it should be 30 because x represents the number of lessons, and 30 is multiplied by that.
Answer:
D. B,C,A
Step-by-step explanation:
A= |7|=7
B= -6
C= |-5|=5
so this means that B<C<A = -6<5<7
so; B,C,A = -6,7,5
I got 70
Combination=n!/((n-r)!r!)
=8!/((8-4)!*4!)
=8*7*6*5*4!/(4!*4!)
=8*7*6*5/(4*3*2)
=70 ways
Answer:
x = 24
Step-by-step explanation:
The formula for determining the sum of interior angles is:


Therefore to determine an equation for x, we must add up all the interior angle equations and set them equal to 720.

The equation and answer above shows how to find x, which equals 24.
