Answer:
The value of RD' is 5 units.
Step-by-step explanation:
It is given that rectangle ABCD was dilated to create rectangle A'B'C'D' using point R as the center of dilation.
The scale factor is the proportion of side length of image and side length of preimage.
Scale factor is also defined as
Multiply both sides by 15.
Therefore the value of RD' is 5 units.

Step-by-step explanation:
An obtuse triangle is the triangle in which one of the side is the longest. It contains an obtuse angle and the longest side is the side that is opposite to the vertex of the obtuse angle.
Let the three sides of the obtuse triangle be a, b and c respectively with c as the longest side. Let a = 9 inches and b = 14 inches.
Now we know that for an obtuse triangle,
c > 16.64
Therefore the smallest possible whole number is 17 inches.
Answer:
Step-by-step explanation:
⟾Collect like terms
- 8x - 10x = x - 45
⟾Move the variable to the left
- - 2x = x - 45
⟾Collect like terms again
- - 2x - x = - 45
⟾Divide both sides by -3
- - 3x = - 45
⟾ x = 45 ÷ 3
- x = 15.
