The number of blocks needed to make the 9th figure in the pattern is 24 and this can be determined by using the given data and arithmetic operations.
Given :
- Dionne builds a pattern that is represented by the equation b = 2f + 6.
- f is the figure number of the pattern.
- b is the number of blocks in each figure.
The following steps can be used to determine the number of blocks needed to make the 9th figure in the pattern:
Step 1 - Write the equation of the pattern that Dionne builds.
[tex]b = 2f+6[/tex]
Step 2 - Now, the number of blocks needed to make the 9th figure in the pattern is:
[tex]b = 2\times 9+ 6[/tex]
b = 18 + 6
b = 24
So, the number of blocks needed to make the 9th figure in the pattern is 24.
