tasks 1...i need this solution as soon as possible..please anyone give me accurate answer

Task Hol The four two- dimensional vectors are Jivan a = be , - lez b = -2e, + 3ez -and the C = 1el + 2ez Ld = _ ze, + le2 tree three - dimensional vectors . f = ye, - lez - 2e3 J. = - 3 e, - 3ez + les h = zeit se2 - le3 (1 ) Determine graphically and mathematically the resultant ( sum ) of the vectors (all and (b ) and state their length ( amount ) ( 2 ) Divide the Sum of a and b. into the , also graphically and arithmetically Directions ( and d. ( 3 ) Determine _ the variable"is contained in the vector Inin Such a way that the Spatial Product of the three vectors f, J and h itake's on the value 6 .
