Answer: x=13
Explanation:
step 1 - multiply both sides by 6 to get rid of it
step 2 - simplify both sides
step 3 - subtract 1.4 from both sides
x = 13
Answer:

Step-by-step explanation:

→ First plus p to both sides to isolate 3a

→ Divide both sides by 3 to isolate a

Answer:
2x² + 6
Step-by-step explanation:
f(g(x)) = 2(g(x))
= 2(x² + 3)
= 2x² + 6
