sorry if am wrong luv!
Answer:
a. 
b. 
Step-by-step explanation:
a. Radius of semicircle (r) = r
Diameter of semicircle (d) = 2r
Length of rectangle (l) = 2*diameter of semicircle = 2*2r = 4r
Distance around the track (p) = circumference of circle + 2(l)
Note: the two semicircles of the track = 1 full circle
Circumference of full circle = πd = π*2r = 2πr
Distance around the track:
p = 2πr + 2(4r)
p = 2πr + 8r
b. Rewriting the formula to make radius, r, the subject of the formula in terms of distance around the track.

Factor out r

Divide both sides by (2π + 8)



Answer:
4(x + 12)
Step-by-step explanation:
The sum of a number and 12 indicates addition. Then, it says that this sum will be multiplied by 4. So, we can use x to represent this random number.
Answer:
x = 24
Step-by-step explanation:
MO is the angle bisector of ∠LMN, thus the following ratios are equal.
=
, that is
=
( cross- multiply )
7x = 12 × 14 = 168 ( divide both sides by 4 )
x = 24
The sides are 11 each because the square root of 121 is 11. So, the permeter is 11 + 11 + 11 + 11 = 44 inches.
Hope this helped!
