Nonlinear Systems of Equations
zheka24 [161]

The square root and cube root identities are proved.

According to the statement

we have to find that the use of the square root identity (x − y)2 = x2 − 2xy + y2

And use of cube root identity a3 + b3 = (a + b)(a2 − ab + b2).

So, For this purpose, we know that the

A. Let us assume the two conditions.

So,

2x + 3y = 6  -(1)

4x + 7y = 8  -(2)

Here we use elimination method

So, Multiply 4 with (1) and 2 with (2)

8x + 12y = 24  

8x + 14y = 16  

Now eliminate x from these equations

-2y = 8

here y is -4.

and the x become

2x + 3y = 6  

2x -12 = 6

2x = 18

x = 9.

B. For the use of identity (x- y)^{2}  = x^{2} - 2xy + y^{2}

Let us assume a number 26 and 28 then fill it in the condition then

(28- 26)^{2}  = 28^{2} - 2(28)(26) + 26^{2}

Then

(28- 26)^{2}  = 784 - 1456 + 676

(28- 26)^{2}  = 4

And we have to prove the cube root identity then

The identity is

a^{3}  + b^{3}  = (a + b)(a^{2} - ab + b^{2})

Then let us assume the number 8 and 9 then

a^{3}  + b^{3}  = (a + b)(a^{2} - ab + b^{2})

8^{3}  + 9^{3}  = (8 + 9)(8^{2} - 8*9 + 9^{2})

8^{3}  + 9^{3}  = (17)(64 - 72 + 81)

8^{3}  + 9^{3}  = (17)(73)

8^{3}  + 9^{3}  = (1241)

Hence by this way we prove the square and cube root identities.

So, The square root and cube root identities are proved.

Answer plss. will mark the first correct answer as brainliest!!
Eva8 [605]

Answer:

(-1,-2, -3, -4)

Step-by-step explanation:

-15 < 3n <6

-15 < 3 (-1,-2, -3, -4) <6

3 • -1 = -3

3 • -2 = -6

3 • -3= - 9

3 • -4 = -12

so all these answer still make -15 the lowest value and 6 the highest value.
