Hope this helps
Step-by-step explanation:
Let's solve your equation step-by-step.
4x+2=2x+12
Step 1: Subtract 2x from both sides.
4x+2−2x=2x+12−2x
2x+2=12
Step 2: Subtract 2 from both sides.
2x+2−2=12−2
2x=10
Step 3: Divide both sides by 2.
2x
2

Answer:
14.13m³
Step-by-step explanation: to get the capacity of the water tank, you have to calculate its volume usong the formula for volume of a cylinder
Volume of the cylinder = πr²h
where r is the radius which is half of the diameter = 3/2 = 1.5m
h is the height which is 2m
π = 3.14
volume = 3.14 x 1.5² x 2
volume = 14.13m³
therefore the capacity is 14.13m³ in cubic meters
Answer:
57.72 ft²
Step-by-step explanation:
Find the area of a semicircle with radius 2 ft. Subtract this from the area of a triangle with base 8 ft and height 4 ft. Add this to the area of a rectangle with width 6 ft and length 8 ft.
Area of semicircle = 
Area of triangle = 
Area of rectangle = width x height = 6 x 8 = 48
Total area = (16 - 6.28) + 48 = 57.72 ft²
