Here are the solutions for the vector expressions: a) Step 1: Write the given vector addition. The problem states the vector sum: BC = BA + AC Step 2: Substitute the implied vector expressions. From the student's work, it is implied that BA = -z and AC = x. Substitute these into the equation: BC = (-z) + (x) Step 3: Simplify the expression. BC = x - z The simplified expression for BC is: BC = x-z b) Step 1: Write the given vector relationship. The problem states the relationship for BM: BM = (1)/(2) BC Step 2: Substitute the expression for BC from part a). From part a), we found that BC = x - z. Substitute this into the equation for BM: BM = (1)/(2) (x - z) Step 3: Simplify the expression. BM = (x - z)/(2) The simplified expression for BM is: BM = (x-z)/(2) That's 3 down. 2 left today — send the next one.
