Step-by-step explanation:
Order the numbers from Smallest to Largest...
9, 10, 14, 15, 19, 21, 21, 27
Then the middle number is your answer.
Since there are 2 Middle Numbers, you add them together, and divide by 2.
Which would be, 17.

True or false:
A linear binomial has a degree of 0
A trinomial has a degree of 2
A constant has a degree of 1
A cubic monomial has a degree of 3
I will mark as the top answers of you help me!
Answer:
The degree of a binomial is zero. The product of two binomials is not a polynomial. The sum of two polynomials is a polynomial. A monomial containing ^2 has a degree of three
The degree of the polynomial is found by looking at the term with the highest exponent on its variable(s). Examples: 5x2-2x+1 The highest exponent is the 2 so this is a 2nd degree trinomial.
Names of Degrees
Degree Name Example
0 Constant 7
1 Linear x+3
2 Quadratic x2−x+2
3 Cubic x3−x2+5
The degree of a cubic monomial is three. A quadratic polynomial is a trinomial. The degree of a binomial is two.

Alaina needs to sell 225 boxes in order to be the top seller. She sells thin mints and samoas to all of her customers for a total of $628.00 in sales. The thin mints sell for $3.00 each and the samoas sell for $2.50 each. Which system of equations below could be used to find how many boxes of thin mints and samoas were sold?
Answer:
94 boxes of samoas
131 boxes of thin mints
Step-by-step explanation:
m=mints
s=samoas
s+m=225 m=225-s
s(2.5)+m(3)=628
2.5s+3m=628
substitute for m
2.5s+3(225-s)=628
2.5s+675-3s=628
reduce
-0.5s=-47
s=94
m=131

Find the area of the base of a box of height 4cm and lateral surface area 120cm.sq if its length is twice its breadth.
Answer:
The area of the base of a box is 1800 cm².
Step-by-step explanation:
We have:
H: is the height = 4 cm
[tex]A_{l}[/tex]: is the lateral surface area = 120 cm
L = 2B
We can find the breadth of the base by using the lateral surface area and the height:
[tex] A_{l} = H*B [/tex]
[tex] B = \frac{A}{H} = \frac{120 cm}{4 cm} = 30 cm [/tex]
Now, if the length is twice its breadth we have:
[tex] L = 2B = 2*30 cm = 60 cm [/tex]
Hence, the area of the base is:
[tex] A_{b} = B*L = 60 cm*30 cm = 1800 cm^{2} [/tex]
Therefore, the area of the base of a box is 1800 cm².
I hope it helps you!

** if there is two responses **
Answer:
m∠CDE = 37°
Step-by-step explanation:
Since, AB║CD and AC is a transversal line.
∠EAB ≅ ∠ECD [Alternate interior angles]
m∠EAB = m∠ECD = 25°
m∠CED + m∠AED = 180° [Linear pair of angles]
m∠CED + 62° = 180°
m∠CED = 180° - 62°
= 118°
By triangle sum theorem In ΔCDE,
m∠CED + m∠CDE + m∠ECD = 180°
118° + m∠CDE + 25° = 180°
m∠CDE + 143° = 180°
m∠CDE = 37°
