Answer:

x = 3

Step-by-step explanation:

5x + 3 = 3x + 9

subtract 3 on both sides (cancels out 3) (inverse operation)

5x = 3x + 6

subtract 3x on both sides (cancels out 3x) (inverse operation)

2x = 6

divide both sides by 2 (isolates x) (simplifies)

x = 3

Answer:

x = 30, x = 5 and x = 9

Step-by-step explanation:

The diagonals of a square are perpendicular bisectors of each other, so

∠ AEB = 90° , then

3x = 90 ( divide both sides by 3 )

x = 30

---------------------------------------------------------

(9)

The 4 angles of a square are right and the diagonals bisect the angles, then

∠ BAC = 45° , so

9x = 45 ( divide both sides by 9 )

x = 5

-------------------------------------------------------

(10)

All sides are congruent , so

CD = AB , that is

3x - 5 = 2x + 4 ( subtract 2x from both sides )

x - 5 = 4 ( add 5 to both sides )

x = 9

$2cosx+2cos2x=0 \\ -2sin^2x+2cos^2x+2cosx=0 \\ -2(1-cos^2x)+2cos^2x+2cosx=0 \\ -2+2cos^2x+2cos^2x+2cosx=0 \\ 4cos^2x+2cosx-2=0 \\ t=cos x \\ 4t^2+2t-2=0 \\ \Delta=4+32=36 \\ t_1= \frac{-2-6}{8}=-1 \\ t_2= \frac{-2+6}{8}= \frac{1}{2} \\ cos x=-1 \lor cos x= \frac{1}{2} \\ x=-\pi \lor x= \frac{5\pi}{3}$
