Masja [62]3 years ago

Answer:

100= 4 + 3 (100-1)

4+3 (99)

4 + 297 is 301

Step-by-step explanation:

The first row starts with 4 toothpicks, and they increase by +3 in each row.  The first tree is already accounted for which makes the 4 + 3, and why I have 100-1.  The teacher said the answer was correct but I doubted the equation.  Can you tell me if this is correct?

Sense this would be known to be a 'prism', we would them do the following key point:

l*w*h

Therefore, we would then multiply to following numbers which would be above.

(5*4*3=60)

Question #2.

The reason to why we would us 'square units' to answer in a area format would be because by doing so, it would then describe the surface of the area. And by knowing what you are measuring something by would be a whole lot easier.
