Which expression is equivalent to n + n - 0.18n
Rudiy27

Answer:

1.82n

Step-by-step explanation:

We combine like terms to simplify this.

Any variable with no other coefficient can be written with a coefficient of 1.  This is because everything can be multiplied by 1 without changing it.  This means we have

1n + 1n - 0.18n

Combining like terms, we have

2n - 0.18n = 1.82n

Find the area of the triangle whose vertices are (0,4) , (0,0) and (2,0) by plotting them on graph
Luden [163]

Refer to the attached image. Since one vertex is the origin and the other two lay on the coordinate axes, the triangle is a right triangle. This means that, if we consider AB to the be base, AC is his height, and vice versa.

Anyway, it means that the area is given by

A = \cfrac{\overline{AB}\times\overline{AC}}{2}

Since AB is a horizontal segment and AC is a vertical segment, their length is given by the absolute difference of the non-constant coordinate: points A and B share the same x coordinate, so we subtract the y coordinates:

\overline{AB} = |2-0| = |2| = 2

The opposite goes for AC: points A and C share the same y coordinate, so we subtract the x coordinates:

\overline{AC} = |4-0| = |4| = 4

So, the area is

A = \cfrac{2\times 4}{2} = 4
