Question 1126825

{{{U = 2i + 5j}}},{{{ V = 5i + 2j}}}, 


{{{U + V = 2i + 5j+5i + 2j}}}
{{{U + V = 7i + 7j}}}
{{{U + V = 7 (j + i)}}}



{{{U- V = 2i + 5j-(5i + 2j)}}}
{{{U - V = 2i + 5j-5i-2j}}}
{{{U - V = -3i+3j}}}
{{{U - V = 3(-i+j)}}}



{{{4U + 2V = 4(2i + 5j) +2(5i + 2j)}}}
{{{4U + 2V = 8i + 20j +10i + 4j}}}
{{{4U + 2V = 18i + 24j}}}
