Answer: 6 - 2z
Step-by-step explanation:
Algebraic expressions are expressions that are represented by variables and constants
The different ways to present algebraic expressions without changing their meaning is by using an equivalent expression
<h3>How to write an algebraic expression differently</h3>
To rewrite an algebraic expression without changing its meaning, we simply rewrite the expression using an equivalent expression.
Assume the expression is:
2x + 3
Another way to write the above expression is:
3 + 2x
This is so because both expressions are equivalent
Hence, the different ways to present algebraic expressions is by using an equivalent expression

Answer:
18
Step-by-step explanation:
because if you add 18 and 17 its 35
The value of card(B) is card(B) = 4954
<h3>How to determine the card(B)?</h3>
The set is given as:
B={1,3,5,7,9,….9907}
The above set is the set of odd numbers from 1 to 9907.
The number of elements is the cardinality
And it can be calculated using
L = a + (n - 1)d
Where
L = 9907
a = 1
d = 2
So, we have:
9907 = 1 + (n - 1)2
Subtract 1 from both sides
9906 = (n - 1)2
Divide by 2
n - 1 = 4953
Add 1 to both sides
n = 4954
This means that
card(B) = 4954

Answer: V = 100.48
Step-by-step explanation:
To get this value, you need to know the formula of the volume of the cone, which is:
V = π*r^2*h / 3
Where:
r: cone radius
h: height
π: value of pi which is 3.14
Now the radius, is half the diameter of base of the cone so:
r = 8 / 2 = 4 units
Now we have all the data needed to get the volume of the cone, let's use the expression given above:
V = 3.14 * (4)^2 * 6 / 3
V = 3.14 * 16 * 6 / 3
V = 301.44 / 3
V = 100.48
