a) What is the perimeter, in centimeters, of the image of RSTV after the dilation?

b) What is the area, in centimeter squares, of the image RSTV after the dilation?

2. Given rectangle ABCD where the perimeter is 12cm and the area is 36cm2. If rectangle RSTV is dilated by a scale factor of 4 about a given center. EXPLAIN YOUR REASONING AND SHOW YOUR WORK

a) What is the perimeter, in centimeters, of the image of RSTV after the dilation?

b) What is the area, in centimeter squares, of the image RSTV after the dilation.

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

yes

yes yes yes

square pyramid

step-by-step explanation:

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base

tetrahedron has a triangular base

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
