Papessa [141]3 years ago
5 0

Answer:

The side lengths cannot belong to a right triangle.

Step-by-step explanation:

This is a simple case of Pythagorean proof. If this triangle was a right triangle, 20^2 + 21^2 = 28^2. However, this is not the case. 20^2 + 21^2 = 841, which square root is 29.

If you forgot, the Pythagoren Theorem is: a^2 + b^2 = c^2.

Hope this helps!

HELP!! 4. (01.02 MC)<br> Which number line shows the solution to -3- (-1)? (1 point)<br> o
statuscvo [17]

Answer:

<em>The third choice gives the correct sequence.</em>

Step-by-step explanation:

<u>The Number Line</u>

To represent numbers in the line, we use arrows starting from the mark for zero up to the given number. If the number is positive, the arrow points to the right and if the number is negative, the arrow points to the left.

The number -3 must be represented as an arrow to the left side of length 3. Subtracting something from the number should also point to the left side, but if the number is negative, then the new arrow points to the right side.

To subtract -1, the arrow should point to the right starting from -3

The third choice gives the correct sequence.
