Final answer:
To simplify (–28xy) ÷ (–4), divide the coefficient and subtract the exponents of the variables. The simplified expression is 7xy.
Step-by-step explanation:
To simplify the expression (–28xy) ÷ (–4), we need to divide the coefficient and subtract the exponents of the variables.
The coefficient of the numerator is -28 and the coefficient of the denominator is -4. Dividing -28 by -4 gives us 7.
The variables in the numerator are x and y, and there are no variables in the denominator. So, the final simplified expression is 7xy.
