Answer:
0 solutions
Step-by-step explanation:
4(x-2)=4x+10
4x-8 = 4x+ 10
-8 = 10 (not true)
(When you have something like 6=7, 0 solutions. If it is like 6=6, infinite solutions. x=6, one solution)
Answer:
Note: The expression "h =300- pi r /pi r" would equate to 299, as written. I find h = (300 - π
)/πr to be the equation for height.
Step-by-step explanation:
The total surface area of a sylinder is 2πr(h+r) where h is the height and r is the radius. That consists of top and bottom disks, each with an area of π
, for a total of 2π
. The side is a continous sheet that has an area of 2πrh, where h is the height. 2πr is the circumference of the can, so the surface area of the side is 2πrh.
The total surace area of a closed cylinder is therefore 2π
+ 2πrh.
2π
+ 2πrh = 600
π
+ πrh = 300
πrh = 300 - π
h = (300 - π
)/πr
Answer:

Step-by-step explanation:
Given a quadratic equation in the form
, you can use the Quadratic formula to solve it. This is:

Then, you need to subtract
from both sides of the equation given:

You can identify that:

Then, substituting values into the Quadratic formula, you get:


Answer:
1.) The diagonal lengths are equal
2.) The diagonals are perpendicular
