2+4z-18
change it so it's an equation
2+4z-18=0
then get 4z alone on one side by subtracting 4z from both sides
2-18=-4z
-16= -4z
divide both sides by -4
a negative divided by a negative becomes positive
4 =z
plug it in
2+4(4)-18
4x4 is 16
2+16-18=0
0=0
the same can be done for the second one 2+k-8
make it 2+k-8=0
move the k to get it alone so subtract k from both sides
2-8=-1k
-6 = -1K
you can divide by K to make K=6
plug in 2+6-8=0
0=0
The answer is C Y=326,000(1.4)x
Explanation: You model the equation by putting the current number of the population in this case 326,000 times the annual rate which is 1.4% by the number of years so it’s represented as 326,000(1.4)x I pray you get the answer correct
The first and the third.

Tan(angle) = Opposite Leg / adjacent leg
tan(37) = x / 10
x = 10 *tan(37)
x = 7.5
