If a+b+c=6,ab+bc+ca=11,then what is a3+b3+c3-3abc
(a+b+c)^3=a^3 +b^3+c^3-2(ab+ac+bc)
216=a^3+b^3+c^3-2(11)
a^3+b^3+c^3=238
but ıdk how can ı find -3abc :/
===============================================
Work Shown:
a+b+c = 6
(a+b+c)^2 = 6^2
(a+b+c)(a+b+c) = 36
a(a+b+c)+b(a+b+c)+c(a+b+c) = 36
a^2+ab+ca+ab+b^2+ca+bc+c^2 = 36
a^2+b^2+c^2+2ab+2bc+2ca = 36
a^2+b^2+c^2+2(ab+bc+ca) = 36
a^2+b^2+c^2+2*11 = 36
a^2+b^2+c^2+22 = 36
a^2+b^2+c^2 = 36-22
a^2+b^2+c^2 = 14
-----------------------
a^3+b^3+c^3-3abc = (a+b+c)*(a^2+b^2+c^2 - (ab+bc+ca) )
a^3+b^3+c^3-3abc = 6*(14 - 11)
a^3+b^3+c^3-3abc = 18

Answer:
∠ CAD = 32°
Step-by-step explanation:
The sum of the angles in Δ ABD = 180°, thus
∠ BAD + 100° + 48° = 180°
∠ BAD + 148° = 180° ( subtract 148° from both sides )
∠ BAD = 32°
Since AD bisects ∠ CAB , then
∠ CAD = ∠ BAD = 32°

a number divided by 3 equals the value of two times the same number subtracted from 2Step-by-step explanation:
Evaluate the expression the quantity 3 plus 5, multiplied by, the quantity h minus k, divided by 4, when h = 4 and k = 12. A –16 B 8 C 20 D 29
Answer:
A is the correct option.
Step-by-step explanation:
We need to evaluate the expression 3 plus 5, multiplied by, the quantity h minus k, divided by 4, when h = 4 and k = 12. It can be written as :
[tex](3+5)\times \dfrac{h-k}{4}[/tex]
Put h = 4 and k = 12 in above expression.
So,
[tex](3+5)\times \dfrac{h-k}{4}=(3+5)\times \dfrac{4-12}{4}\\\\=8\times \dfrac{-8}{4}\\\\=2\times -8\\\\=-16[/tex]
After solving we get that the value of the given expression is -16.

Amy invested $250 in the bank and a year later has $285.72. By what percent has the amount changed?
Answer:
14.28 %
Step-by-step explanation:
It is given that,
Initial amount is $250 and after 1 year the amount is $285.72. We need to find the percent by which the amount changed. It can be calculated as follows :
[tex]\%=\dfrac{\text{change in amount}}{\text{initial amount}}\times 100\\\\\%=\dfrac{285.72-250}{250}\times 100\\\\\%=14.28\%[/tex]
Hence, there is an increase of 14.28 % in this case.

To prove : m∠ABC = m∠GHI
Given,
∠ABC ≅ ∠DEF
∠GHI ≅ ∠DEF
Here,
∠ABC ≅ ∠DEF
∠GHI ≅ ∠DEF
∠DEF ≅ ∠ABC (Symmetric property)
∠GHI ≅ ∠ABC (transitive property)
m∠GHI = m∠ABC (definition of ≅ angles)
m∠ABC = m∠GHI ( symmetric property)

In an arithmetic sequence, the first term is 2 and the second term is 5. Find the common difference.
Answer:
d = 3Step-by-step explanation:
In an arithmetic sequence the common difference is always the difference between the next term and the previous term:
[tex]d= a_2-a_1=a_3-a_2=...=a_{150}-a_{149}=....[/tex]
we have: [tex]a_1=2\quad and\quad a_2=5[/tex]

a rectangluar rug has a length that is 3 times its width. The perimieter is 56 feet. what are the dimensions?
Answer:
7 x 21
Step-by-step explanation:
We can say that the dimensions are a and b. Since this is a rectangle, we know that the perimeter will be 2a + 2b. So our first equation is:
2a + 2b = 56.
They also tell us that the length is 3 times its width. So we can say this:
a = 3b.
Now we can substitute, and we can do the full problem with the given info:
2a + 2b = 56
a = 3b
2a = 6b
6b + 2b = 56
8b = 56
b = 7
Now that we know b, we can multiply it by 3 to get a:
b = 7
a = 3b
a = 21.
So our answer is:
a = 21
b = 7
Answer:
Dimensions:
7 x 21
Answer:
Width=7
Length=21
Step-by-step explanation:
p=56 feet
L=3W
P=2L + 2W
56=2(3W)+2W
56=6W+2W
56=8W
W=56/8 = 7 ⇒ Width=7
L=3W
L=3*7
L=21 feet ( length=21 feet)
check : p=2l+2w
P=2(21)+2(7)
p=42+14=56
In a cyclic quadrilateral ABCD, if (∠B – ∠D) = 60o , show that the smaller of the two is 60o
ANSWER
It is given that ABCD is a cyclic quadrilateral
(∠B−∠D)=60
o
......(1)
(∠B+∠D)=180
o
.....(2)
By adding both the equations
∠B−∠D+∠B−∠D=60
o
+180
o
So we get
2∠B=240
o
By division
∠B=120
o
By substituting equation it in equation (1)
(∠B−∠D)=60
o
120
o
−∠D=60
o
On further calculation
∠D=120
o
−60
o
by subtraction
∠D=60
o
Therefore, the smaller of the two angles ∠D=60
