Answer:
A. x-6
Step-by-step explanation:
Maybe you want to simplify ...
((6x)/(10x^2))/(6/(10x^3 -60x^2))
Invert and multiply. Cancel common factors from numerator and denominator.

Step-by-step explanation:
Solving for the surface area of the cube:
2² (5 faces) = 20 ft²
Solvig for the surface area of the pyramid:
0.5 (2ft) (3ft) (4 faces) = 12 ft²
Total surface area = 20 + 12 = 32 ft²
12 - x = 5
Subtract 12 from both sides
12 - 12 - x = 5 - 12
- x = - 7
Divide both sides by -1
-x/-1 = -12/-1
x = 7
Answer:he swam 120 meters
Step-by-step explanation:
Using Pythagoras rule x^2=50^2-30^2
X^2=2500-900
X^2=1600
X=√(1600)
X=40
Total distance=30+50+40
Total distance=120 meters
