<u>Basic answer</u>
When is a quadrilateral a square?
When it has four right angles and four congruent sides.
<u>Geometry Answer (just in case, since the question is vague)</u>
How can you prove if a quadrilateral is a square?
It is a square if it is both a rectangle and a rhombus.
It is a rectangle if
a) It has a right angle and is a parallelogram
b) It has congruent diagonals and is a parallelogram
c) It has four right angles
It is a rhombus if
a) It has two adjacent sides congruent and is a parallelogram
b) Its diagonal bisects opposite angles and it is a parallelogram
c) Its diagonals perpendicular bisect each other
It is a parallelogram if
a) Two pairs of opposite sides parallel
b) Two pairs of opposite sides congruent
c) One pair of sides both congruent and parallel
d) The diagonals bisect each other
e) Two pairs of opposite angles congruent
Answer:
-2 ≤x≤5
Step-by-step explanation:
The domain is the inputs
The lowest value of x is -2 and every value of x is valid up to 5
-2 ≤x≤5
Given:
Radius of a cylinder = 5 units.
Surface area of the cylinder = 
To find:
The height of the right cylinder.
Solution:
Surface area of a cylinder is:
Where, r is radius and h is the height of the cylinder.
Putting 
in the above formula, we get
Subtract 
from both sides.
Divide both sides by 
.
Therefore, the height of the cylinder is 11 units.
A, 2 since side a is xroot 3 and side b is just the x
1/3 rise=1 run=2. Therefore the answer is 1/3
