Answer: m^3/8+3m^2n/2+6mn^2+8n^3 Hope that helps!
Step-by-step explanation:
1. Use cube of sum : (a+b)^3=a^3+3a^2b+3ab^2+b^3
(m/2+2n) ((m/2)^2+2×m/2×2n+(2n)^2)
2. Use division distributive property: (x/y)^a= x^a/y^a
(m/2+2n)(m^2/2^2+2×m/2×2n+(2n)^2)
3. Simplify 2^2=4
(m/2+2n)(m^2/4+2×m/2×2n+(2n)^2)
4. Use multiplication distributive property (xy)^a= x^a y^a
(m/2+2n)(m^2/4+2×m/2×2n+2^2n^2)
5. Simplify 2^2=4
(m/2+2n)(m^2/4+2×m/2×2n+4n^2)
6. Cancel 2
(m/2+2n)(m^2/4+m×2n+4n^2)
7. Regroup terms
(m/2+2n)(m^2/4+2mn+4n^2)
8. Expand by distributing sum groups
m/2(m^2/4+2mn+4n^2)+2n(m^2/4+2mn+4n^2)
9. Expand by distributing terms
m^3/8+m^2n+2mn^2+2n(m^2/4+2mn+4n^2)
10. Expand by distributing terms
m^3/8+m^2n+2mn^2+nm^2/2+4n^2m+8n^3
11. Collect like terms
m^3/8+(m^2n+m^2n/2)+(2mn^2+4mn^2)+8n^3
12. Simplify.
And your answer would be m^3/8+3m^2n/2+6mn^2+8n^3

Which of the following is equal to 2?
A. 6 + 4 ÷ (2 + 1) × 3
B. (6 + 4 ÷ 2) – 1 × 3
C. 6 + (4 ÷ 2) + 1 × 3
D. (6 + 4) ÷ 2 – 1 × 3
Answer:
D
Step-by-step explanation:
Start with the values inside parentheses.
6 + 4 = 10
10 / 2 = 5
Then subtract 1*3.
5 - 3 = 2
*B is incorrect because according to order of operations, 4/2 should be calculated before adding 6.

Help plz..And No links!! I repeat No links!!
Answer:
The answer is 276.32 square yards.
Step-by-step explanation:
To solve for the surface area of a cylinder, use the surface area of a cylinder formula, which is SA= 2[tex]\pi[/tex]rh + 2[tex]\pi[/tex][tex]r^{2}[/tex]. However, instead of using ([tex]\pi[/tex]), 3.14 will be used.
Next, plug in the information from the question into the formula. The formula will look like SA= 2(3.14)(4)(7) + 2(3.14)([tex]4^{2}[/tex]). Then, solve the equation, and the final answer will be 276.32 square yards.

Michelle falou que tem 5 anos e que sua irmã tem 13 e seu pai 35 e sua mãe tem tres anos amenos que seu pai .Quantos anos a família tem ao total?
Responder:
85 anos
Explicação passo a passo:
Dado :
Idade de Michelle = 5 anos
Idade da irmã = 13 anos
Idade do pai = 35 anos
Idade da mãe = idade do pai - 3 = 35 - 3 = 32 anos
Idade total se a família:
(Idade de Michelle + idade da irmã + idade da mãe + idade do pai)
(5 + 13 + 35 + 32) = 85 anos
points, segments, rays and lines
Answer:
B, E
Step-by-step explanation:
The lines at the top represent line, ray, or segment.
Since line UV is a segment, it includes the normal line. And, you can flip UV to VU so...B and E!

which set of sides will NOT make a triangle?
12cm, 7cm, 5cm
2cm, 3c, 4cm
11cm, 13cm, 3cm
19cm, 14cm, 7cm
please I've been looking for an answer to this question
Answer:
x = 9cm
using sine rule
a/sine(A) = b/sine(B)
a= x; A= 64° ( alternating angles)
b= 10 cm ; B = 90°
x/sine(64) = 10/sine(90)
x= {10 × sin(64)}/ sin 90
x = 9cm
Answer:
650

3. A class rolled number cubes. Their results are shown in the table. What is the experimental probability of rolling the number 1? Round your answer to the nearest tenth.
17.2%
16.4%
15.7%
17.5%
Answer:
15.7%
Step-by-step explanation:
Experimental probability is the probability of something that is determined by doing an experiment.
To find the probability, divide the number of rolling a one and add all the occurrences of every other result.
So,
42 / (42 + 44 + 45 + 44 + 47 + 46) =
42 / 268 =
0.156716 =
15.6716
Rounded to the nearest tenth, the probability of rolling a one would be 15.7%.

At the electronics emporium, 10 CDs are on sale. Marie can only afford to buy 3 CDs. How many combinations of CDs are possible?
Answer:
120 combinations of CDs are possible
Step-by-step explanation:
The total combinations could be
[tex]10C_3[/tex]
[tex]\frac{10*9*8*7!}{7!*3!}[/tex]
On further expanding, we get -
[tex]\frac{10*9*8}{3!} \\\frac{10*9*8}{3*2*1} \\= 10*3*4\\= 120[/tex]
Hence, 120 combinations of CDs are possible

Michelle’s house is 22 miles due north of Jan’s house and 30 degrees northeast of Richard’s house. Richard’s house is due east of Jan’s house. How far is it from Michelle’s house to Richard’s house?
Answer:
Michelle’s house is 44 miles to Richard’s house.
Step-by-step explanation:
The distance can be found out by using the trigonometric ratio of sine theta
Sine theta= Perpendicular/ Hypotenuse
We know the values of hypotenuse and theta
Sine 30 = 22/ Hypotenuse
Hypotenuse= 22/ sine 30
Hypotenuse= 22/0.5
Hypotenuse = 44
The hypotenuse marks the distance between Michelle’s house to Richard’s house. Due east means counter clockwise rotation from east.

Find the volume. I need answer answer ASAP
Answer:
[tex]A=448[/tex]
Step-by-step explanation:
To find the volume of the given figure, one must multiply the lengths of all sides together. Therefore, set up an equation and solve,
[tex]V = (l)(w)(h)[/tex]
(V) indicates volume, (l) indicates the length of the base, and (h) indicates the height of the figure.
Substitute,
[tex]V=(8)(14)(4)[/tex]
Solve,
[tex]A=448[/tex]
