Answer:
The perimeter is approximately 18 units.
Step-by-step explanation:
The dilation causes the rectangle to shrink, so the side lengths shrink as well. The side with 10 units go down to 7.5, and the sides with 2 units go down to 1.5.
These numbers multiplied by 2 and then added together gives an answer of 18 units.

A. Yes
B. Yes
C. No
D. No
=======================================================
x = number of minutes
y = amount of rope uncoiled
At first we have 50 feet of uncoiled rope. So basically at time x = 0 we have y = 50 feet of uncoiled rope. The point (0,50) is on the line. After 5 minutes, 5*10 = 50 feet of rope is coiled up, as its coiled at 10 ft/min. After these 5 minutes, we have 0 feet of uncoiled rope. The point (5,0) is on the line.
The line goes through (0,50) and (5,0)
Now go through the window options and see which provide the right window to be able to see the line segment with the endpoints mentioned.
- Choice A = yes, because y = 50 is part of the interval
- Choice B = yes, similar reasons as choice A
- Choice C = no, due to the fact that y = 50 is too large and outside the interval
- Choice D = no, same reasoning as choice C
10 of each of the other sides but the last one is 2 inches
Answer:
(x + 5)(3x + 5)
Step-by-step explanation:
(x - 5)(x + 8) + (x + 5)(2x - 3) ← factor out (x + 5) from each term
= (x + 5)(x + 8 + 2x - 3)
= (x + 5)(3x + 5)
