Solve forx: 10 (2x - 4) + 5 = 2r - 8 1 ОА. x =- 19 10 O B. x= =- 1 С O c. x = 1 O D. x = =

Option D

Step-by-step explanation:

Given expression is,

10(2x - 4) + 5 = 2x - 8

By using distributive rule,

20x - 40 + 5 = 2x - 8

20x - 35 = 2x - 8

Now we subtract 2x from both the sides of the equation

20x - 35 - 2x = 2x - 8 - 2x

18x - 35 = -8

By adding 35 on both the sides of the equation

18x - 35 + 35 = - 8 + 35

18x = 27

By diving with 18 from both the sides of the equation

x =

Therefore, Option D will be the correct option.

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
