Answer:
Step-by-step explanation:
Total area will be sum of two areas
5x²-6x+4 + 15x²+8x+2
20x²+2x+6
Total area
[tex] = ({5x}^{2} - 6x + 4) + ( {15x}^{2} + 8x + 2)[/tex]
[tex] = {5x}^{2} - 6x + 4 + 15 {x}^{2} + 8x + 2[/tex]
[tex] = ( {5x }^{2} + {15x}^{2} ) + ( - 6x + 8x) + (2 + 4)[/tex]
[tex] = {20x}^{2} + 2x + 6[/tex]
