Answer:
B.
Explanation:
A and C have awkward sentence structure because "when a car needs many serious repairs, it might be cheaper to buy a new car", it repeats the word car again making it redundant and in C, "When a car had needed many serious repairs, it might be cheaper to buy a new one", it has wrong use of past-tense.
That is false because parents can do a lot.
Answer:
15
Explanation:
(x-5)(x+5)=200
FOIL Method (First, Outer, Inner, Last)
x^2-5x+5x-25=200
combine like terms
x^2-25=200
add 25 to both sides
x^2 = 225
Take the square root of both sides
x=15
