Question

Help ive been stuck for a long time please

Answer 1

Step-by-step explanation:

Area of small rectancle =

$x \times (x - 4) = {x}^{2} - 4x$

Area of big rectangle =

$(2x + x)(x - 2)$

${2x}^{2} - 4x + {x}^{2} - 2x$

${3x}^{2} - 6x$

Total area =

${3x}^{2} - 6x + {x}^{2} - 4x$

${4x}^{2} - 10x$

${4x}^{2} - 10x = 36$

simplifying by 2,

${2x}^{2} - 5x = 18$

${2x}^{2} - 5x -18 = 0$
