Let
The origin of coordinates the tree
r1 = vector position of the child 1.
r2 = vector position of the child 2
Child 1:
r1 = (12i + 12j)
Child 2:
r2 = (-18i + 11j)
The scalar product will be given by:
r1.r2 = ((12) * (- 18)) + ((12) * (11)) = - 84
The scalar product of their net displacements from the tree is -84m ^ 2
The answer is c. You can plug in the values for x and y and see which ones equal up to 5!
Answer:
we conclude that in the second step, 3 should have been subtracted from the right side as well on the left side.
Step-by-step explanation:
Given the expression

SECOND STEP
subtract 3 from the right-hand side as well as on the left-hand side

SOLVING THE REMAINING COMPLETE COMPRESSION

Divide all parts by -2
- Please note that multiply or divide an inequality by a negative number flips the inequality sign.
so the expression becomes


Hence, from the explanation, we conclude that in the second step, 3 should have been subtracted from the right side as well on the left side.
