2(x + 2) + 1= 5(-x + 8)

x = 5

Step-by-step explanation:

2(x + 2) + 1= 5(-x + 8)

2x + 4 + 1 = -5x + 40

2x + 5x = 40 - 4 - 1

7x = 35

x = 35/7

x = 5

idk im srry

step-by-step explanation:

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
