Answer:

<h3>X=4.8</h3>

Step-by-step explanation:

Isolate x on one side of the equation.

x/-12=-0.4

x(-12)/-12=(-0.4)(-12) (First, multiply by -12 from both sides.)

(-0.4)(-12) (Solve.)

(-0.4)(-12)=4.8

x=4.8

So, the final answer is x=4.8.

Does the choice of the base affect the area of the triangle
icang [17]
Yes the base of a triangle greatly affects the area of the triangle. Half of the base times the height of a triangle equals its area, so therefore the base greatly affects it.<span />
