ANSWER
The algebraic expression that is a polynomial with a degree of 2 is

EXPLANATION
The degree of a term of a polynomial is the total sum of the exponents of the variables in each term.
The highest degree of the polynomial is considered the degree of the polynomial.
For first option,

the highest degree is 3.
The second option is,

This polynomial also has a degree of 3.
The third option is,

This last option has a degree of 2.
Therefore the correct answer is option C.
1st number = x
2nd number = y
2x + y = 26
-
x + y = 10
x = 16
26 - (2 x 16) = -6
10 - 16 = -6
Number 1 is 16
Number 2 is -6
Answer:
A. 10cm
B. 8 times
Step-by-step explanation:
The question is on volume of a conical container
Volume of a cone= 
where r is the radius of base and h is the height of the cone
Given diameter= 12 cm, thus radius r=12/2 =6 cm

h=10 cm
B.
If height and diameter were doubled
New height = 2×10 =20 cm
New diameter = 2×12 = 24, r=12 cm
volume = 
To find the number of times we divide new volume with the old volume

Answer:
A. 4
Step-by-step explanation:
We can look at the number line and find B and A
we get
B=-7
A=3
now, we can find |B| and |A|


now, we can find
|B|-|A|
now, we can plug values


So,
option-A
