b) (b, -c)

c) (-b, c)

d) (-b, -c)

Answers

Answer 1

Answer:

The coordinate of the point C will be (b, c). Then the correct option is A.

What is regular pentagon?

The polygon which is having five sides and each side are congruent. And each internal angle of the Pentagon will be of 108 degrees.

The pentagon ABCDE with the coordinate of A, B, C, D, and E are given below.

If a line intersect the shape and the shape look identical on both sides of line, then the line is known as axis of symmetry.

In a regular pentagon, there are five line of symmetry.

In the figure, the y-axis is the axis of symmetry and the axis of symmetry is passing through the point D.

The point C is in the first coordinate, then the abscissa and ordinate will be positive.

Then the coordinate of the C will be (b, c).

Then the correct option is A.

In the following steps student made the error in the third step.

What is an Equation ?

An equation is a mathematical term, which indicates that the value of two algebraic expressions are equal. There are various parts of an equation which are, coefficients, variables, constants, terms, operators, expressions, and equal to sign.

The error occurred in Step 3.

Step 3 should be:

-2(m) = -2(6 + n)

-2m = -12 - 2n

The mistake was that the student distributed the negative sign only to the 6 and not to the n.

The correct next step is to simplify equation 2:

2m = 8 + 8n

So the student made an error in Step 3.
