Question

ayudaa hallar el area

Answer 1

Respuesta:

As = -x² + 7x +17

Explicación paso a paso:

si es el área sombreada, entonces:

A1 = (x+4) * (x+6)

A1 = x²+6x+4x+24

A1 = x²+10+24

A2 = (x-1)²

A2 = x²-2x+1

A3 = (x+2) * (x+3)

A3 = x²+3x+2x+6

A3 = x²+5x+6

A sombreada= A1 - A2 - A3

As = (x²+10x+24) - (x²-2x+1) - (x²+5x+6)

As =  x² + 10x + 24 -x² + 2x -1 -x² -5x -6

As = -x² + 7x +17
