What is are if a rectangle of length of 5 and width of 3x-5y+6what is the area of a rectangle with a length of 5 and a width of 3x-5y+6

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:

From given,

Length = 5

Width = 3x - 5y + 6

Substituting the values in formula, we get,

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

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
