Yasin performs the elementary row operation represented by R2 - Ri on matrix A. 4 3 0 А 6 -3 12 What matrix results from this transformation? Enter your answer by filling in the boxes. Enter any fractions as simplified fractions. Next​

The length of what is left would be 1 1/2 feet long.

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
