C. By three feet 7x5=35 area 7x10=70 area 7+3=10
Answer:
39
Step-by-step explanation:
(16-2w)^2 + (3y÷3z)
Let w=5 y=9 and z=3
(16-2*5)^2 + (3*9÷3*3)
PEMDAS says parentheses first
Multiply and divide in the parentheses
(16-10)^2 + (27÷9)
Then add and subtract in the parentheses
(6)^2 + (3)
Now the exponent
36 +3
39
It looks like the first 1 is the first problem, problem #1. (because of the period)
If this is the case, then the second sequence is 1, 0, -1, ...
1-1=0
0-1=-1
-1-1=-2
-2-1=-3
-3-1=-4
The sequence would then be 1, 0, -1, -2, -3, -4, ...
Answer:
The population in 2017 is 171 million
Step-by-step explanation:
Let's assume population starts from 1991
so,
initial population is 147 million
so, 
we can use formula

we can plug A=147

In 1998:
t=1998-1991=7

now, we can plug these values into formula and find k

Divide both sides by 147





now, we can plug it back
and we get

In 2017:
t=2017-1991=26
we can plug it and find P


So,
The population in 2017 is 171 million
