d, if the egg is not fertilized
Explanation:
The level of hormones remains elevated when fertilization has taken place and the embryo is required to be implanted over the wall of the uterus. The increase in progestrone and estrogen levels causes the endometrium wall of the uterus to be thicken, the progesteron release also makes the mucus of the cervix to be thicken so that the sperms and bacteria remain prevented from entry inside the uterus.
In the absence of fertilization the level of hormones remain low. The corpus luteum degenerates after 14 days, menstrual cycle begins and the level of estrogen and progesteron remains low.

Step-by-step explanation:
Side 1 = a
Side 2 = b
Side 3 = c
a = 2b
c = 5ft. + b
a + b + c = 49 feet
Substitute
2b + b + 5ft + b = 49 ft
Add the b’s
4b + 5ft = 49ft
Subtract 5ft from both sides of the equation
4b = 44ft
Divide both sides of the equation by 4 to isolate b
b = 11ft
a = b * 2 = 11 * 2 = 22ft
c = 49ft - 11ft - 22ft = 16ft
Hope this helps :)
