Answer 1

Answer:

Step-by-step explanation:

Total area will be sum of two areas

5x²-6x+4 + 15x²+8x+2

20x²+2x+6

Answer 2

Total area

$= ({5x}^{2} - 6x + 4) + ( {15x}^{2} + 8x + 2)$

$= {5x}^{2} - 6x + 4 + 15 {x}^{2} + 8x + 2$

$= ( {5x }^{2} + {15x}^{2} ) + ( - 6x + 8x) + (2 + 4)$

$= {20x}^{2} + 2x + 6$
