" 11."quad [bar(b)=bar(a)],[mx-ny=m^(2)+n^(2);x+y=2m]

Solve for x and y : mx- ny = m^(2) + n^(2) " " x - y = 2n

solve the following pair using cross multiplication method mx+ny=m^(2)+n^(2) and x+y=2m

Solve the following system of equations by method of cross-multiplication: mx-ny=m^(2)+n^(2),quad x+y=2m

If quad 0.bar(82) and y=0.bar(17),A=0.bar(7),B=0.bar(2) then [(x+y)+(A+B)]^((x+y)+(A+B)) is

If |bar(a)|=|bar(b)|=|bar(c)|=2 , and bar(a)*bar(b)=bar(b).bar(c)=bar(c)*bar(a)=2 then [bar(a) bar(b) bar(c)] = (1). 3sqrt(2) (2). 4sqrt(2) (3).32 (4).48

If bar(a)=2bar(i)-bar(j)+3bar(k), bar(b)=-bar(i)+4bar(j)-2bar(k), bar(c)=5bar(i)+bar(j)+7bar(k) and xbar(a)+ybar(b)=bar(c) then (x, y) =

If bar(a),bar(b) are non collinear vectors such that bar(p)=(x+4y)bar(a)+(2x+y+1)bar(b) that of bar(q)=(y-2x+2)bar(a)+(2x-3y-1)bar(b), find x & y such that 3vec p=2vec q

The formula |bar(a)+bar(b)|^(2)=|bar(a)|^(2)+|bar(b)|^(2)+2bar(a)xx bar(b) is valid for non-zero vectors bar(a) and bar(b) .
