SOLUTION: if x=2/3 is a root of 6x^2+kx-2=0. find the valie of k and the other root 2. solve for M in the equation. 3^4(m+1)+ 3^4m=246 3. The sides of a rectangle are xcm and (x+1)

Question 1031607: if x=2/3 is a root of 6x^2+kx-2=0. find the valie of k and the other root

2. solve for M in the equation. 3^4(m+1)+ 3^4m=246
3. The sides of a rectangle are xcm and (x+1)cm. A circle has a radius of (x+2)cm. The sum of the area of the rectangle and the circle is 184cm. Using π as 22/7 find the value of x.

2. solve for M in the equation. 3^4(m+1)+ 3^4m=246
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 = 246,  --->

 = 246,  --->

 = 246,

 =  = 3,  --->

4m = 1  --->  m = .
