Which example illustrates the associative property of addition for polynomials? [(2x2 + 5x) + (4x2 – 4x)] + 5x3 =
(2x2 + 5x) + [(4x2 – 4x) + 5x3]

[(2x2 + 5x) + (4x2 – 4x)] + 5x3 =
[(4x2 – 4x) + (2x2 + 5x)] + 5x3

(2x2 + 5x) + [(4x2 – 4x) + 5x3] =
(2x2 + 5x) + [5x3 + (4x2 – 4x)]

[(2x2 + 5x) + (4x2 – 4x)] + 5x3 =
[(5x + 2x2) + (–4x + 4x2)] + 5x3

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

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.

brainliest

the answer is a if my teacher taught me correct

add a pic of the graph, then ill edit this "answer" and solve it for you : 3
