Answer 1

Answer:

Answer:

You may or may not need to include the units.

A = 18x - 18

P = 6x + 6

Graph is attached below. (2, 18)

Step-by-step explanation:

Substitute the information we need, "l" and "w", into the formulas.

l is for length, 6cm.

w is for width, (3x - 3)cm.

Use the formula for area of a rectangle.

A = lw

A = (6)(3x-3)cm²

A = (18x - 18)cm² or 18x - 18

Use the formula for perimeter of a rectangle.

P = 2(l + w)

P = 2(6 + (3x - 3))cm

P = 2(3x + 3)cm

P = (6x + 6)cm or 6x + 6

Linear equations are written in the form y = mx + b, so we do not need to factor or further simplify the formulas.

To graph, first turn the "m" value into a fraction form.

8 -> 8/1

6 -> 6/1

You need two points to graph each line.

For each equation, the first point is on the y-axis at the "b" value. Then use the "m" in the equation to count the number of units up (numerator) and to the right (denominator).

The solution is (2,18)

The Reflexive Property of Congruence lets you say that ∠PQR ≅ _____.

Answers

Answer:

< PQR

Step-by-step explanation:

Reflexive Property of Congruence says that something is equal to itself

Answer:

∠PQR is congruent to itself i.e

∠PQR ≅ ∠PQR

Step-by-step explanation:

Given that according to Reflexive Property of Congruence

we have to tell about ∠PQR ≅ _____.

The reflexive property of congruence states that any figure i.e geometric figure congruent to itself.

The properties includes

A line segment has the same length, an angle has the same angle measure, and a geometric figure has the same shape as itself.

The reflexive property of equality simply states that a value is equal to itself i.e

∠PQR is congruent to itself i.e

∠PQR ≅ ∠PQR

An original piece of artwork is 2.75 feet by 2.25 feet a reprint of the artwork is 22 inches by 18 inches are the pieces similar? if so what is the ratio of their corresponding side lengths?

Answers

Yes, the Repainted Artwork is similar to the Original. The 22*18 inch repaint can be recaclculated into a 1.83*1.5 feet repaint. Both can be multiplied by about 1.5 to equal 2.75*2.25. Therefore, the ratio is 1.5.
