Accepted Answer

Hello, everyone. We are asked to determine the value of the given expression. We are given 17 P minus eight Q and P equals negative three, Q equals negative six. Our answer choices are a negative three B three C 99 D negative 99. So beginning again with the expression 17 P minus eight Q, we are told P equals negative three. So we're gonna rewrite this as 17 multiplied by negative three minus eight, multiplied by the value of Q which is negative six. Now multiplying 17 by negative three. A positive multiplied by a negative is a negative. So this will be negative 51 and then multiplying negative eight by negative six will give us a positive 48 because a negative multiplied by a negative is a positive and adding these to today together negative 51 plus positive 48 will give us a negative three. So our answer here is negative three which is answer choice. A have a nice day.
