What is the answer to 5(2x+1)=2x+21

5(2x + 1) = 2x + 21

Multiply the 5 into (2x + 1)

10x + 5 = 2x + 21

Subtract 2x on both sides to get the "x" on one side of the equation

8x + 5 = 21

Subtract 5 on both sides

8x = 16

Divide 8 on both sides to get "x" by itself

x = 2

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°
