Answer:
x = 729/4 = 182.250
Step-by-step explanation:
FEMORAL TRIANGLE is the triangle that is an important arterial pressure point for controlling lower limb hemorrhage.
The femoral triangle is located in the thigh. This is the region where the femoral artery, vein, and nerve travel through. Thus, it being a significant arterial pressure point.
I believe it has 5 faces.
x = -4, so use the first equation, x^2 = -4^2 = -16
x = 4, use 3rd equation, sqrt(x) = sqrt(4) = 2
D) 311.2 ft2
8×4=40/2=20×2=40 + 18×8=144 = 184 + (3.14)81/2=254.34/2=127.17 + 184 = 311.17 which rounds 311.2 ft2
