We know that the lengths of the two smaller sides have to be more than the third side when they are added together
The third side couldn't be 2 or 3 because 9 (7+2) or 10 (7+3) are not less than 10
The third side couldn't be 17 or 18 because 17 (7+10) is not larger than 17 or 18
The correct answer is C. 4 works because 7+4=11 or more than 10. 16 works because 7+10=17 is more than 16
Hope this helps
-2log_5 7x = log_5 2
log_5[1/(7x)^2] = log_5 2
log_5(1/49x^2) = log_5 2
log_5(1 - 49x^2) = log_5 2
1 - 49x^2 = 2
You finish.
The answer is D. I hope this helps love! :)
ANSWER

is the third degree polynomial.
EXPLANATION
The third degree polynomial has the highest degree to be 3.
All the polynomials were written in standard form.

is a first degree polynomial.

is a second degree polynomial .

is a third degree polynomial.

is a fourth degree polynomial.
Answer:
Step-by-step explanation:
a =3 ;r = 1/2
first term = 3
second term = 3*1/2 = 3/2
third term = 3/2 * 1/2 = 3/4
Fourth term = 3/4*1/2 = 3/8
Fifth term = 3/8 * 1/2 = 3/16
GP is: 3,3/2,3/4,3/8,3/16......
