Answer:
1) Area of larger region = (3x-5)(3x-5)
Area of smaller region = (x+1)(x+1)
Subtract area of smaller region from area of larger region:
⇓
⇓
⇓
2) Length of shaded region = a³ - b³
Width of shaded region = a² + ab +b²
(But )
So,
⇓
Final factored form for perimeter =
(But )
So, the final factored form for Area =
Step-by-step explanation:
