The expression −9k−3−9k−4 can be simplified by combining the like terms.
The terms −9k and −9k can be added together to get −18k.
Similarly, the terms −3 and −4 can be added together to get −7.
Therefore, the simplified expression is −18k−7.
Among the given multiple choice answers, the expression −7−18k is also equivalent to −18k−7.
To find the expression that is equivalent to −9k−3−9k−4, we can simplify the expression by combining like terms.
Step 1: Start with the given expression: −9k−3−9k−4
Step 2: Group the like terms together. In this case, we have two sets of like terms: −9k terms and the constant terms.
Step 3: Combine the like terms in each group. For the −9k terms, you can add the coefficients (-9 - 9) and keep the variable k as it is. This gives us -18k. For the constant terms, you can add the coefficients (-3 - 4) to get -7.
Step 4: Rewrite the simplified expression using the combined like terms: -18k - 7.
Therefore, the expression that is equivalent to −9k−3−9k−4 is -18k - 7.
To simplify the expression −9k−3−9k−4, we can combine like terms.
Combining −9k and −9k, we get −18k.
So, the simplified expression is −18k−3−4.
Combining −3 and −4, we get −7.
Therefore, the equivalent expression is −7−18k.
So, the correct answer is:
−7−18k
