Step-by-step explanation:
<em>Combine like terms</em>
a. 2r + 3 + 4r = (2r + 4r) + 3 = 6r + 3
b. 8 + 3d + d = (3d + d) + 8 = 4d + 8
c. mn + (-3mn) + 6 = (mn - 3mn) + 6 = -2mn + 6
d. 10s + (-10) + (-4s) = (10s - 4s) - 10 = 14s - 10
<em>Terms are called "like terms" if they have the same variable part (the same letters in the same powers). Like terms differ at most coefficient.</em>

Answer:
the answer is A
Step-by-step explanation:
A logarithm of a number is the exponent to which the base of the logarithm must be taken to equal the number.
Example the logarithm (log) to the BASE 10 of 100 is 2 because
10^2 = 100
The log to base 10 of 1000 = 3 as 1000 = 10^3
The log to the base 3 of 9 is 2 because 9 = 3^2
- or we can say 2 is the log to base 3 of 9.
