6
The 6 is the constant because it is never going to change
f(x), and others that contain x will change based on the value x
Since 6 doesn’t have the c with it it will be constant
The sum of AB and BC is 180 degrees. So 13x - 10 = 180. 13x = 190.
x = 190/13
I have worked out the answer to the question, I hope it helps you. Please do not forget to check if this answer if reliable, I am not always correct
Gonna go with D.i think u just have to add all the miles
(7^5 * 7^3)^4 * 7^-2 / 7^-7 * 7^20
= (7^8)^4 * 7^-2 / 7^(-7 + 20)
= 7^32 * 7^-2 / 7^13
= 7^(32 - 2) / 7^13
= 7^30 / 7^13
= 7^(30 - 13)
= 7^17
