Add 7 to both sides. 4x=36. 36/4 is 9. So x=9.

Use the identity x3+y3+z3−3xyz=(x+y+z)(x2+y2+z2−xy−yz−zx) to determine the value of the sum of three integers given: the sum of
fenix001 [56]

ffn

x^3+y^3+z^3-3xyz=(x+y+z)(x^2+y^2+z^2-xy-yz-zx)

x^3+y^3+z^3-3xyz=(x+y+z)(x^2+y^2+z^2-(xy+yz+zx))

the sum of their squares is 110, So x^2+y^2 + z^2= 110

the sum of their cubes is 684, so  x^3+y^3 + z^3= 684

the product of the three integers is 210, so xyz= 210

the sum of any two products (xy+yz+zx) is 107

Now we plug in all the values in the identity

x^3+y^3+z^3-3xyz=(x+y+z)(x^2+y^2+z^2-(xy+yz+zx))

684 - 3(210) = (x+y+z)(110-107)

684 - 630 = (x+y+z)(3)

54 = 3(x+y+z)

Divide by 3 on both sides

18 = x+y+z

the value of the sum of three integers is 18

please help me A portion of Taquan's check register is shown. Before Taquan made his utility payment on March 24, the balance of
Natalka [10]

The check register is used to show the total amount Taquan spent

Using the assumed values, Taquan's initial balance is $1336.26

<h3>How to determine the amount before making the utility payment?</h3>

The question is incomplete, as the check register is not shown.

So, I will give a general explanation

Assume that the utility bill is $241.46

From the question, the new balance on March 24 is $1094.80

This means that the initial balance is:

Initial balance = New balance + Utility bill

This gives

Initial balance = $1094.80 + $241.46

Evaluate the sum

Initial balance = $1336.26

Using the assumed values, Taquan's initial balance is $1336.26

Question 3<br> 1) What is the slope of the line?<br> YA<br> 1<br> AX
Kipish [7]

Answer:

Slope: 2

Step-by-step explanation:

Taking any two points on the slope: (0,1) & (1,3)

where (0,1) is (x1,y1) and (1,3) is (x2,y2)

Substituting into the slope formula as below:

\frac{y2-y1}{x2-x1}

= (3-1)/(1-0)

= 2/1

= 2

Hence, the slope is 2
