Answer:

2.

4x^2 + 4 - 5x + x - 2x^2 + 8

= (4x^2 - 2x^2) + (x - 5x) + (4 + 8)

= 2x^2 - 4x + 12

=> D is correct

3.

2x^2 + 6x - 7x + 8 - 3x^2 + 1

= (2x^2 - 3x^2) + (6x - 7x) + (1 + 8)

= -x^2 - x + 9

=> C is correct

4.

B is correct (4 and 3)

Hope this helps!

kifflom [539]

You can use the pythagorean theorem.

a^2+b^2=c^2

a=9

b=b

c=41

9^2+b^2=41^2

81+b^2=1681

b^2=1600

b=+/-40

but since this is a geometric scenario, answers will only lie in the positive real number set. That's why answer is +40 or C.
