9x^2-4
F.(3x + 2)(3x - 2)
G.(3x + 2)2
H. (3x - 2)2
J. prime

Step-by-step explanation:

I'm not entirely sure what the question is, but I suspect the answer is not prime.

9x^2 - 4

factors into two factors  (3x + 2)(3x - 2)

Suppose x = 11 which is prime.

9*121 - 4

1085 which ends in a 5 so the expression is not prime.

In fact, the two factors are 3*11 + 2 = 35  and 3*11 - 2 = 31

31*35 = 1085

9514 1404 393

  F.  (3x +2)(3x -2)

Step-by-step explanation:

The given expression is the difference of two squares, so can be factored accordingly.

  9x^2 -4 = (3x)^2 -2^2 = (3x +2)(3x -2) . . . . . matches F

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this

da freeck kinda math is this just drop out
