Step-by-step explanation:
step 1. 15^18/15^3
step 2. 15^18*15^-3
step 3. 15^(18 - 3)
step 4. 15^15
X + (7 + 14x) = 15x + 7
hope this helps
I think the first one is correct. Since “three less than z squared” insinuate that the value is 3 units less than the value z^2
-10.4
subtract 5.2 on each side because it’s the inverse operation
hope this helps!
