When using factoring by grouping, the replacement terms will both have the same sign of the original middle term. If the last term is negative, then the signs of the factors will have one of each sign with the “stronger” number (the larger absolute value) matching the middle term. hope this helps
M(2)+2=J
Mary is half the height so multiply by 2 then add the extra 2 inches
Ex: 38inches(2)+2=78inches
You're right on B. So if there are 27 pairs of sandals (starting with 9 pairs of sandals) you would divide 27 by 9 which is 3. Use 3 again and multiply it by 5 which is 15.
Idk but if anyone does know it because im stuck too!
