Hello :)
In this problem, you have to create an equation to figure out the length of each bar. The first bar has two sets of 3 blocks; you can see each set by a color change.
Therefore, this equation would be 2 times 3, since there are 2 sets of 3. This answer equates to 6.
The next one has two bars of four blocks. This means it is 2 times 4, because there are two sets of 4 blocks, and this would constitute as the answer 8.
The second question is a bit tricker. If we look at the first bar, we see that there are 3 blocks per set (noted by color change) and we have 3 of those. If we count all of those up, they have 9 blocks overall. After all, 3 times 3 is nine.
The other problem has 4 blocks a set, and there are three of those. 4 times 3 is 12.
4(2y+5) + (-6-4y)
