Answer:

2r

Step-by-step explanation:

2r is the answer because:

We have to switch the -3r in to +3r and positive + positive = positive.

Then we change the add sign in to subtracting sign and we subtract:

3r-5r and  it will give us:

2r

And we keep the answer positive  because our answer was a +5r so the bigger number keeps the sign  the same.

The legs of a right triangle XYZ are 5 cm and 12 cm. Triangle XYZ is dilated to triangle X'Y'Z' by a scale factor of 2/3 . What
allochka39001 [22]

Assuming that the base is 5 cm and the height is 12 cm, so by dilating the legs by a scale factor of 2/3, the new dimensions are:

 

base = 5 cm * (2 / 3) = 10/3 cm

height = 12 cm * (2 / 3) = 8 cm

 

So the area of a right triangle is calculated using the formula:

A = b h / 2

A = (10/3) * 8 / 2

<span>A = 13.33 cm^2</span>
