D₀,₃ (x , y), where:
D stands for dilatation. the sub (0) = center and the sub (3) represents the scale factor. The scale factor "k" being 3, means the actual image has been dilated 3 times versus the pre-image or reciprocally, the pre-image is a reduction of the image by a factor k₁= 1/3
The coordinate of A' in the image A(-3, 6)
The coordinate of A in the pre-image should be A(-3.k₁, 6k₁)
But k₁ =1/3, then A(-3/3 , 6/3) = A(-1 , 2) (Second Answer)
Add and subtract the second term to the expression and factor by grouping.

Yes, because they all have 5 as a common denominator.
Answer:
if ∠Q=∠R
draw an angular bisector from P to QR in which it intersect wit Qr at point S
now we have two triangle : QPS and RSP
in which angle : QPS=RPS ( PS is angular bisector)
and we have angle Q and angle R are equal
and PS is common side
this makes triangle QPS and RSP are congruent by AAS(angle angle side)
which also means that pQ=PR ( proved)
Answer:
4
Step-by-step explanation:
360 deg = 20
1 deg = 20/360
72 deg = 20/360 * 72 = 4
