Answer:
2. C.
3. B.
4. C.
5. A.
6. D.
7. B.
Step-by-step explanation:
2. Review what a polynomial is.
3. 2x²+4x-2 = 2(1)² + 4(1) -2 = 2+4-2 = 4
4. 3x - 2y + 5 = 3(2) - 2(4) + 5 = 6 - 8 + 5 = 3
5. (3x + 5) + (4x - 1) = 7x + 4
6. 2^n • 2^n = 2^n (1 + 1 ) = 2^n (2¹) = 2^n+1
7. Study the laws of exponent.
