Simplify the equation by combining like terms:

7x²+ 4x - x²

Solve:

7x²+ 4x - x²

7x² and -x² are like terms, so combine them.

6x² + 4x

There are no more like terms, so your answer would be: 6x² + 4x

Answer:

6x² + 4x

Juli2301 [7.4K]

Answer:

3x+2y

Step-by-step explanation:

Find the rectangles attached

Area of a rectangle = Length * Width

A = A1+A2

given

A = 30cm²

A1 = 3 * x

A1 = 3x

A2 = 2*y

A2 = 2y

Substitute

30 = 3x+2y

Hence the required equation is 3x+2y = 30
