hii

Step-by-step explanation:

3(x-2)-2x+3=-12

3 times x = 3x

3 times -2 = -6

3x-6-2x+3=-12

3x + 2x = 5x

-6 + 3 =-3

i don't know the rest I'm sorry

[Right Triangles Only] SOHCAHTOA[Right Triangles Only] tanθ = opposite over adjacent

Step-by-step explanation:

Step 1: Define

Angle θ = 70°

Opposite Leg = x

Adjacent Leg = 6

Step 2: Solve for x

Substitute in variables [tangent]: $\displaystyle tan70^\circ = \frac{x}{6}$ [Multiplication Property of Equality] Isolate x: $\displaystyle 6tan70^\circ = x$ Rewrite: $\displaystyle x = 6tan70^\circ$ Evaluate: $\displaystyle x = 16.4849$ Round: $\displaystyle x \approx 16.5$
