Substitute w = 1 and w = 3 to determine if the two expressions are equivalent. 4 (3 w + 4) 16 w + 12 Which statements are true? Check all that apply. The value of both expressions when w = 1 is 28. The two expressions are equivalent. The value of both expressions when w = 1 is 16. The two expressions are not equivalent. The value of both expressions when w = 3 is 52. The value of both expressions when w = 3 is 60.

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°

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153

true

step-by-step explanation:

it is more then likely a review to you prepare for an upcomign test or quiz

false

inverse variation is not exponential
