The side lengths of a rectangle are all multiplied by 5. What happens to its perimeter?
stiv31 [10]

Answer:

The perimeter is multiplied by 5.

Step-by-step explanation:

Perimeter of a rectangle:

The perimeter of a rectangle with sides l and w is given by:

P = 2(l + w)

The side lengths of a rectangle are all multiplied by 5.

This means that l = 5l, w = 5w. So

P_M = 2(5l + 5w) = 2*5(l+w) = 10(l + w)

What happens to its perimeter?

The rate is:

\frac{P_M}{P} = \frac{10(l+w)}{2(l+w)} = 5

The perimeter is multiplied by 5.

The rule Rx-axis o is applied to the point (-3,-2). Where is the image in the coordinate
Nastasia [14]

Answer:

Image = (-3,2)

Step-by-step explanation:

Given

Point = (-3,-2)

Transformation = Rx-axis

Required

Determine the image

When rule Rx-axis is applied to a point (x,y),

The new coordinate point is (x,-y)

<em>In other words, the y coordinate is negated</em>

So, when rule Rx-axis is applied to

Point = (-3,-2)

The image of the point is

Image = (-3,-(-2))

Image = (-3,2)
