Neporo4naja [7]2 years ago
6 0

Answer:

{x,y}={6,-1}

Step-by-step explanation:

Solve by Substitution :

// Solve equation [2] for the variable  y

[2]    y = -x + 5

// Plug this in for variable  y  in equation [1]

  [1]    x - 2•(-x +5) = 8

  [1]    3x = 18

// Solve equation [1] for the variable  x

[1]    3x = 18

[1]    x = 6

// By now we know this much :

   x = 6

   y = -x+5

// Use the  x  value to solve for  y

  y = -(6)+5 = -1

Solution :

{x,y} = {6,-1}

a rectangle has a height of n3+4n2+3n and a width of n^3+5n^2 express the area of the entire rectangle
alukav5142 [94]

<u>Given</u>:

It is given that the height of the rectangle is n^3+4n^2+3n

The width of the rectangle is n^3+5n^2

We need to determine the area of the entire rectangle.

<u>Area of the rectangle:</u>

The area of the rectangle can be determined using the formula,

A=height \times width

Substituting the values, we have;

A=(n^3+4n^2+3n)(n^3+5n^2)

Multiplying each term within the parenthesis, we get;

A=n^{3} n^{3}+n^{3} \cdot 5 n^{2}+4 n^{2} n^{3}+4 n^{2} \cdot 5 n^{2}+3 n n^{3}+3 n \cdot 5 n^{2}

Simplifying, we get;

A=n^{6}+5 n^{5}+4n^{5}+20 n^{4}+3  n^{4}+15 n^{3}

Adding the like terms, we have;

A=n^{6}+9n^{5}+23 n^{4}+15 n^{3}

Thus, the area of the entire rectangle is n^{6}+9 n^{5}+23 n^{4}+15 n^{3}

Can some one help me. The QN is SIMPLIFY BY RATIONALISING DENOMINATOR.
WITCHER [35]

Answer:

\frac{10}{3} - \frac{2\sqrt{7} }{3}

Step-by-step explanation:

Rationalise the denominator by multiplying the numerator/ denominator by the conjugate of the denominator

the conjugate of \sqrt{7} + 5 is \sqrt{7} - 5, hence

12 / (\sqrt{7} + 5) × (\sqrt{7} - 5 ) / (\sqrt{7} - 5)

= (12\sqrt{7} - 60 ) / - 18

= \frac{10}{3} - \frac{2\sqrt{7} }{3}
