What is the value of 8 1/7+5 3/7+4 2/7+3 1/7

If x=(7+5sqrt(2))^(1/3)-1/((7+5sqrt(2))^(1/3)) , then the value of x^3+3x-14 is equal to 1 b. 0 c. 2 d. 4

If x=(sqrt3+1)/2 find the value of 4x^3+2x^2-8x+7

((a)/(b))^(x-1)=((b)/(a))^(x-3), then the value of x is (1)/(2) b.1 c.(7)/(2) d.2

If x=root(3)(7+5sqrt(2))-(1)/(root(3)(7+5sqrt(2))), then the value of x^(3)+3x-14 is equal to 1 b.0 c.2 d.4

If x:y=7:3, then the value of (xy+y^(2))/(x^(2)-y^(2)) is (3)/(4) b.(4)/(3) c.(3)/(7) d.(7)/(3)

If (x+7)^(3)+(2x+8)^(3)+(2x+3)^(3)=3(x+7) (2x+8)(2x+3) , then what is the value of x? (a) -3.6 (b) .6 (c) 2.4 (d) -2.4

If [2x+y,4x,5x-7 4x]=[7 7y-13 y x+6] , then the value of x+y is x=3 , y=1 (b) x=2 , y=3 (c) x=2 , y=4 (d) x=3 , y=3
