Answer: x = -2
Step-by-step explanation: 3x+7 = -x-1; add 1 to both sides: 3x+8=-x; subtract 3x from both sides: 8 = -4x; divide by -4 on both sides: -2 = x
17 - x = 11
X➗2 = 3
5 + x = 11
Lateral surface area of a cylinder: 2πrh, r is the radius, h is the height.
area of the top and bottom circle: πr²
when h=2r, the total surface area is:
2πr(2r)+πr²+πr²=6πr²
the answer is 6πr²
To solve this, we are going to set up a simple rule of three: If 20% are 48 cars, 100% how many cars will be:

Now, we can express this as a proportion ans solve for

:


We can conclude that there are 240 cars in the parking lot.
Answer:
See image
Step-by-step explanation:
Let w=width
And let l=length
Perimeter is the distance all the way around the outside of the shape. Add up all the sides to find it.
