Please help me answer this

Hello!

3(x + 3) = 18

⇒ Step 1 - Multiply everything in the brackets by 3:

3x + 9 = 18

⇒ Step 2 - Subtract 9 from both sides of the equation:

3x + 9 = 18

     - 9    - 9

3x = 18

⇒ Step 3 - Divide both sides of the equation by 3.

x = 6

x = 3

Step-by-step explanation:

1. Distribute.

2. Subtract 9 from BOTH sides.

3. Simplify.

4. Divide BOTH sides of the equation by the same term.

5. Simplify.

Therefore, your answer is X = 3

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

3/5

step-by-step explanation:

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.
