Step-by-step explanation:

\left \{ {{5x-4y=12} \atop {3x+6y=66}} \right.

A = \left[\begin{array}{cc}5&-4\\3&6\end{array}\right]

A_{x} = \left[\begin{array}{cc}12&-4\\66&6\end{array}\right]

A_{y} = \left[\begin{array}{cc}5&12\\3&66\end{array}\right]

The perimeter of a rectangle is 70. The length of the rectangle is represented by (x+3) and the width is represented by (3x-8).
otez555 [7]

Answer: length = 13

Width = 22

Step-by-step explanation:

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(length × width)

The length of the rectangle is represented by (x+3) and the width is represented by (3x-8). If the perimeter of a rectangle is 70, it means that

2[(3x - 8) + (x + 3)] = 70

Dividing both sides of the equation by 2, it becomes

3x - 8 + x + 3 = 35

3x + x - 8 + 3 = 35

4x - 5 = 35

4x = 35 + 5 = 40

x = 40/4

x = 10

Length = x + 3 = 10 + 3

Length = 13

Width = 3x - 8 = 3 × 10 - 8

Width = 22
