V= 15(cos60°i + sin60°j) u = 25(cos30°i + sin30°j) find the magnitude of the sum of v and u. round to the nearest hundredth. a) 6.32 b) 7.39 c) 33.32 d) 38.72

1.
2. v+u=
3. v+u=
4. The magnitude of the sum u+v is =38.72
D is correct choice

Remember, you can do anything to an equation as long as you do it to both sidesminus 36 from both sides4.5(8-x)=66-2.5(3x+24)distribute36-4.5x=66-7.5x-60add like terms36-4.5x=-7.5x+6add 7.5x to both sides36+3x=6minus 36 from both sides3x=-30divide both sides by 3x=-10
