Answer:
10
Step-by-step explanation:
Half of 10 is 5. 5+5 is 10
Answer: +42x
Step-by-step explanation:
The student only multiplied each term individually.
He should have (7x+3)² = (7x+3)(7x+3)
Which is 49x²+42x+9
Therefore the error is (42x) or the failure to apply the law of multiplication of variables in a bracket.
The answer is 0.9 because if you divide 0.018 and 0.02 you would get 0.9
Well, if point C is dilated by 5/3, C' should be (3*5/3, -6*5/3)
This is equivalent to Option A, (5, -10)
