If you try to draw the solid being described above, you will see that the sides (given to be triangular) will meet at a common vertex. The solid is therefore a pyramid. Given that the base is a triangle, the pyramid is more specifically referred to as TRIANGULAR PYRAMID.

frozen [14]

Answer:

The second statement is Correct.

Step-by-step explanation:

Consider the provided information.

It is given that Antonio uses a calculator to find 38-\frac{44-16}{4} and gets a result of –10.

38-\frac{44-16}{4}=38-\frac{28}{4}

=38-7

=31

So, the first statement is incorrect.

2nd statement: Antonio found the answer for 38-44-\frac{16}{4}

38-44-\frac{16}{4}=-6-4

38-44-\frac{16}{4}=-10

The second statement is Correct.

Third statement: Antonio found the answer for \frac{38-44-16}{4}

\frac{38-44-16}{4}=-5.5

So, the third statement is incorrect.

Fourth statement: Antonio found the answer for 38+\frac{44-16}{4}

38+\frac{44-16}{4}=38+7

38+\frac{44-16}{4}=45

So, the fourth statement is incorrect.

Hence, the second statement is Correct.
