Question 1

Choose the one alternative that best completes the statement or answers the question.
-Given $a = - 2 , b = - 10$, which of the following statements is false?
A) $| a / b | = a / b$
B) $| a | + b \mid = - ( a + b )$
C) $\mid a b l = - a b$

Accepted Answer

The absolute value of a product $|ab|$ is always non-negative, regardless of the signs of $a$ and $b$. Since $a = -2$ and $b = -10$, $ab = 20$, and thus $|ab| = 20$, which is not equal to $-ab = -20$.

Question 2

Show that the points P1(2,4), P2(5,2), and P3(7,5) are the vertices of a right triangle.

Accepted Answer

The answer of Show that the points P1(2,4), P2(5,2), and...
