Answer with explanation:</h2>
In the given diagram , here are two circles .
The center of larger circle is at C and the center of the small circle is at B.
Also, the small circle is intersecting the bigger one at two points i.e. at A and D.
Since the distance from the center of the circle to its boundary is the radius of the circle.
∴ Length of AB is same as length of BD [ ∵Radii of same circle are congruent.]

Step-by-step explanation:
Answer: Length = 9 in
Width = 12 in
Step-by-step explanation:
Length L = 3 + W
Perimeter P = 42 in
Perimeter = 2L + 2W
plugin values:
42 = 2(3 + W) + 2W
42 = 6 + 2W + 2W
42-6 = 4W
W = 36 / 4
W = 9
solve L by substituting the value of W=9 into the equation:
L = 3 + W
L = 3 + 9
L = 12
therefore, the dimensions of the rectangle:
Length = 9 in
Width = 12 in
The boat makes 120 mile trip downstream in 3 hours, but makes the return trip in 4 hours. If b-the rate of the boat in still water and c= the rate of the current, the following equations represents the trip upstream; <span>4(b - c) = 120. The answer will be B.</span>
