-12-5(x + 4) = 3x
So like idk how to do this-

x=-4

Step-by-step explanation:

First distribute -5 to x+4 so -5•x and -5•4 get you -5x and -20 then bring every thing down

Now you have

-12-5x-20=3x

Then combine like terms which are -12 and -20 giving you -32

-32-5x=3x and 5 to bot side now you have

-32=8x then divide by 8 on both side giving you -4

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

answer: i dont know but if you try hard you will get it right : )
