Answer:
Q8. (D) 9x²
Q9. (A) [tex]\frac{5}{17}[/tex]
Q10. (C) 10x²-9x+2
Step-by-step explanation:
Q8. Area of new canvas = (3x)(3x)
= 9x²
Q9. Since F is the midpoint of line XY,
6x = [tex]\frac{1}{3}[/tex](x+5)
18x = x+5
17x = 5
∴x = [tex]\frac{5}{17}[/tex]
Q10. Area of rectangle = (2x-1)(5x-2)
= 10x²-5x+2-4x
= 10x²-9x+2
