Could someone help me with a few simple questions? Please?! Anyone?!

Question 1

[7.06] Choose the correct simplification of 9x2(4x + 2x2 − 1).

a) 18x4 + 36x3 − 9x2

b) 18x4 − 36x3 + 9x2

c) 36x4 + 18x3 − 9x2

d) 36x4 − 13x3 + 9x2

Question 2

[7.04] Choose the correct simplification of 2^7/2^4

a) 6

b) 1/8

c) 1/6

d) 8

Question 3

[7.02] Choose the correct simplification of (7x3 − 8x − 5) + (3x3 + 7x + 1).

a) 10x3 − x − 4

b) 10x3 + x + 4

c) 4x3 − 15x − 6

d) 4x3 + 15x + 6

Question 4

[7.07] Choose the correct product of (5x + 3)2.

a) 25x2 − 9

b) 25x2 + 30x + 9

c) 25x2 + 9

d) 25x2 − 30x + 9

Question 5

[7.06] Choose the correct simplification of (8x + 5)(3x − 7).

a) 24x2 − 41x − 35

b) 24x2 + 41x + 35

c) 24x2 + 41x − 35

d) 24x2 − 41x + 35

Question 6

[7.06] Choose the correct simplification of (6x + 4y)(9x − y).

a) 54x2 + 30xy − 4y2

b) 54x2 − 30xy + 4y2

c) 54x2 + 30xy + 4y2

d) 54x2 − 30xy − 4y2

9x2(4x + 2x2 − 1) = .c) 36x4 + 18x3 − 9x2

2^7/2^4 = d) 8

(7x3 − 8x − 5) + (3x3 + 7x + 1) = a) 10x3 − x − 4

(5x + 3)2 = b) 25x2 + 30x + 9

(8x + 5)(3x − 7). = a) 24x2 − 41x − 35

(6x + 4y)(9x − y) = a) 54x2 + 30xy − 4y2
