36-(b^2+c^2-2bc)=36-(b-c)^2=6^2-(b-c)^2= (6+b-c)[6-(b-c)]=(6+b-c)(6-b+c)
Answer: It should be 14 girls
Step-by-step explanation:
35/5=7
2*7=14
5 x 10^5 = 500,000
2 x 10^5 = 200,000
The scientific notation 5 x 10^5 is 2.5 times greater than the scientific notation of 2 x 10^5.

Answer:
B. 66°
Step-by-step explanation:
The remote exterior angle (z) is the sum of the measures of the interior angles (x, y).
x + y = z
(5n -19) +(n +7) = (144 -6n)
12n = 156 . . . . . . . . . . . . . . . . . add 6n+12
n = 13 . . . . . . . . . . . . . . divide by 12
Then the measure of the remote exterior angle is ...
m∠z = (144 -6(13))° = (144 -78)°
m∠z = 66°
__
x = 46°
y = 20°
Answer:
Step-by-step explanation:
This is our quadratic:

where s(t) is the position of the object after all the stuff on the right side happens to it. If the object lands on the ground after all that stuff happens to it, its height is 0. Subbing in a 0 for s(t) gives us:

and if the object hits the ground at 21 seconds, we can sub in a 21 for each t to get this:
and do the math.
and solving for the height:
h = 1845.9 meters
