<span>Simplifying 4x + 8y = 30.60 Solving 4x + 8y = 30.60 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-8y' to each side of the equation. 4x + 8y + -8y = 30.60 + -8y Combine like terms: 8y + -8y = 0 4x + 0 = 30.60 + -8y 4x = 30.60 + -8y Divide each side by '4'. x = 7.65 + -2y Simplifying x = 7.65 + -2y</span>

Jet001 [13]

Answer:

Area= 5x^2-18x -8

Step-by-step explanation:

If the rectangle show one side of length 5 x +2, and another side of length x - 4, then the area of this rectangle (given by the product of the sides' length) is:

Area = (5x+2)\,(x-4)\\Area = 5x^2-20x+2x-8\\Area= 5x^2-18x -8

which is already written in standard form.
