The area of rectangle is 15x - 25y + 30 sqaure units

Solution:

Given that, a rectangle with a length of 5 and a width of 3x - 5y + 6

To find: Area of rectangle

The area of rectangle is given by formula:

$Area = length \times width$

From given,

Length = 5

Width = 3x - 5y + 6

Substituting the values in formula, we get,

$Area = 5 \times (3x - 5y + 6)\\\\\text{Multiply 5 with each term inside the bracket }\\\\Area = 5(3x) -(5)(5y) +5(6)\\\\\text{Simplify the above expression }\\\\Area = 15x -25y + 30$

Thus area of rectangle is 15x - 25y + 30 sqaure units

Dimas [21]

Answer:

-2/3x

Step-by-step explanation:

1.) use the slope equation (y2-y1)/(x2-x1)

2.) substitute the points into the equation (2-4)/(2--1)

3.) solve the equation (2-4= -2) / (2--1=3)

4.) the slope is -2/3
