Solve the equation 4(x + 2)= 6x + 4
SIZIF [17.4K]

The answer is x=2

show you step-by-step

step 1:simplify both sides of the equation.

(4)(x)+(4)(2)=6x+4

4x+8=6x+4

step 2:subtract 6x from both sides.

4x+8-6x=6x+4-6x

-2x+8=4

step 3: subtract 8 from both sides

-2x+8-8=4-8

-2x=-4

step 4: divide both sides by -2

-2x/-2= -4/-2

x=2

that helps you

Find the value of tan theta if sin theta = 12/13 and theta is in quadrant 2
ivanzaharov [21]

Answer:

اhello : tan θ = - 12/5

Step-by-step explanation:

tan θ = sin θ / cos θ .... (*)

(cosθ)² + (sinθ)² = 1   ... (**)

theta is in quadrant 2 : cosθ ≤ 0

Substitute sinθ = 12/13  into (**) and solve for cosθ :

(cosθ)² + (12/13)² = 1  

(cosθ)²  = 1   - 144/169

(cosθ)²  = 25/169

cosθ = - 5 /13  because  cosθ ≤ 0

by (*) : tan θ = (12/13)/ (-5/13) = (12/13) ×(-13/5)

tan θ = - 12/5
