Answer:
The set U includes all positive integers from 1 to 20.
a)
<u>x is subset U and 14 < x ≤ 23, then x is:</u>
- x = {15, 16, 17, 18, 19, 20}
b)
<u>x is subset U and includes multiples of 4, so x is:</u>
Answer:
21x

-2x²(-5x² +4x³) =
10x⁴ - 8x⁵ =
-8x⁵ + 10x⁴ ←<span>standard form
Answer: B)</span>
-4x^2 it is -4 times 1 ( in front of x) and then combine both x's
