Answer:

Answer:
The answer is 14z
Step-by-step explanation:
25z - 8z + (-3z)
-8z + (-3z) is the same thing as -8z - 3z, which equals -11z,
25z - 11z = 14z
A = 21/2 i will write something too just to fill up the space
log(4) + log(2) - log(5)
= log(2²) + log(2) - log(5)
= 2 log(2) + log(2) - log(5)
= 3 log(2) - log(5)
= log(2³) - log(5)
= log (2³/5)
= log (8/5)
= log (1.6) = 0.2041... (rounded)
