Answer:
21x - 42, see below :)
Step-by-step explanation:
Hello!
We know that f(x) is equal to 3x - 6
We want to know what 7 * f(x) is so we should first substitute f(x) for 3x - 6
7 * f(x)
7(3x-6)
We use distributive property to open the parenthesis:
7 * 3x + 7 * -6
21x - 42
Answer: 81, 243, 729
Step-by-step explanation:
<u>STEP ONE: Find a pattern in the sequence</u>
3 ÷ 1 = 3
9 ÷ 3 = 3
27 ÷ 9 = 3
As we can see from the given sequence, each number multiplies 3 to get the next term.
<u>STEP TWO: Find the next three terms</u>
27 × 3 = 81
81 × 3 = 243
243 × 3 = 729
Hope this helps!! :)
