Answer:
Step-by-step explanation:
4a² b³ * (9a⁴b² - 4a² + 3) = 4a²b³ * 9a⁴b² - 4a²b³*4a² + 4a²b³*3
= 36a²⁺⁴ b³⁺² -16a²⁺²b³ + 12a²b³
= 36a⁶b⁵ - 16a⁴b³ + 12a²b³
9r - 6 = 8r + 3
r = 9
EF = 4r + 19 = 4(9) + 19 = 36 + 19 = 55
hope it helps
Answer:
x > 0
Step-by-step explanation:
Domain of a function is defined by the set of x-values of the graph of a function.
From the graph attached,
x-values are starting from x > 0 [Since x ≠ 0] and moves towards infinity,
Therefore, domain of the function will be,
(0, ∞) Or x > 0
