C and D would be the answer
The area of the sidewalk is 144.44 m².
The 2-m wide walk adds 4 m to the diameter, making it 21+4=25.
Since the radius is half the diameter, r = 25/2 = 12.5.
The area of the entire bed with walkway is 3.14(12.5)² = 490.625 m².
The diameter of the bed is 21, so the radius is 21/2 = 10.5.
The area of just the flower bed is 3.14(10.5)² = 346.185.
The difference between the two is 490.625-346.185 = 144.44 m². This is the area of the walkway.
given,
1st term(a)= -2
2nd term (t2) =-12
3rd term (t3) =-60
4th term(t4)= -120
here common ratio (r)=t2/t1=t4/t3
or, -12/-2= -120/-60
or,6=2
hence,no -12, -60, -120 aren't in a geometric sequence because their common ratio aren't same.
Answer:
103
Step-by-step explanation:
We substitute x with 5:

Solve the exponent first:

<em>Note: We are using order of operations (consecutively)</em>
- <em>Parentheses </em>
- <em>Exponents</em>
- <em>Multiplication</em>
- <em>Division</em>
- <em>Addition </em>
- <em>Subtraction</em>
Multiply:
25 * 4 = 100
Add:
100 + 3 = 103
Our answer is 103
