Is the expression 42 undefined? If not, find
the quotient.
-7​

Answers

Answer:

-6*-7=42 wdym as in undefined

Step-by-step explanation:

Final answer:

The expression 42/-7 is not undefined and the quotient of this operation is -6.

Explanation:

The expression 42/-7 is not undefined because it involves division by -7, which is not zero—the key criterion for an undefined mathematical operation. In this case, when 42 is divided by -7, the result is a well-defined quotient, which is -6. Therefore, performing the division operation demonstrates that the expression indeed possesses a valid answer. This highlights the importance of distinguishing between dividing by zero, which results in an undefined outcome, and dividing by non-zero numbers, where a clear mathematical solution, such as -6 in this case, can be determined.

We want to know what is the basis of al units in tne metric system. The metric system is a set of decimal-based prefixes that have the effect of multiplication or division by the integer power of ten. Which means that when we have some unit like a meter or a kilogram, to get to the smaller unit we need to divide by the integer power of ten or when we want a greter unit we need to multiply the unit by the integrer power of ten. So the corret answer is D.
