Answer:
x=30
Step-by-step explanation:
Since the measure of an exterior angle is equal to the sum of any two angles in a triangle, the equation would be 4x-18=2x+6+36. Solve this, and we get x=30.
Hope this helped!
She is incorrect
the GCF of 2, 4 and 8 is 2 (not 8 has she has written)
the GCF of x2, xy and xy4 is x not x2y4
Correct GCF of the 3 terms is 2x
P(y)=ir^t
233=231r^(1999-1991)
(233/231)^(1/8)=r
p(y)=231(233/231)^((y-1991)/8) so in 2003
p(2003)=231(233/231)^((2003-1991)/8)
p(2003)=231(233/231)^(1.5)
p(2003)=234
So 234 million (to the nearest million people)
The simplified expression is 16
B, is the correct answer :))))
