14 - 2n = -32
32 + 14 = 2n
46 = 2n
46/2 = n
23 = n
Checking:
14 - 2(23) = -32
14 - 46 = -32
-32 = -32 (Matched, answer is correct n = 23)
The answer is D because absolute value is always positive
Factor the polynomial:
4u² – 20u + 25
Rewrite – 20u as – 10u – 10u, and then factor it by grouping:
= 4u² – 10u – 10u + 25
= 2u * (2u – 5) – 5 * (2u – 5)
= (2u – 5) * (2u – 5)
= (2u – 5)² <––– this is the answer.
I hope this helps. =)
1/2 of 14 is 7. multiply 14/1 to 1/2.
