Answer:

<h2>Pentagon, regular.</h2>

Step-by-step explanation:

The given figure is a polygon which is a figure with at least three sides which enclose certain area.

If a polygon has three sides, it's called a triangle.

If a polygon has four sides, it's called a quadrilateral.

If a polygon has five sides, it's called a pentagon.

Now, polygons can be regular or irregular, this depends on the equivalence of its sides, if the polygon has all equal sides, then it's called regular polygon.

In this case, we have a polygon with 5 equal sides, therefore it's a pentagon, which is a regular polygon with 5 equal sides.

Therefore, the right answer is the last choice.

Which value of x makes the following equation true?

inysia [295]

Distribute the 2 to all terms within the parenthesis

2(x + 8) = 2x + 16

2x + 16 = x + 20

Isolate the x. Subtract x from both sides and 16

2x (-x) + 16 (-16) = x (-x) + 20 (-16)

2x - x = 20 - 16

Simplify. Combine like terms.

x = 4

C. 4 is your answer

Answer:

Each highlighter is $1.30

Step-by-step explanation:

First the formula is 10+4h=15.20. H represents the unknown cost of each highlighters. Solve for h by subtracting 10 on both sides. 4h=15.20 Then divide 4 on both sides to get h by itself. h=1.30 Therefore one highlighter would cost $1.30

The graph of f(x) is shown. Estimate f(–3).

Aneli [31]

You have to look for -3 on the x axis, and then proceed vertically (in this case upwards) until you meet the graph.

We land about 1/2 square above the 12 mark on the y axis. Since one square is 1/2 unit, a half square would be 1/4 unit.

So, we can estimate $f(-3)\approx 12.25$
