Perimeter = 2w + 2l
2(8x+2) + 2(6x + 6)
Use distributive property
16x + 4 + 12x + 12
Combine like terms
28x + 16
Solution: 28x + 16
Answer: a³ - 218
<u>Step-by-step explanation:</u>
(a - 6)(a² + 6a + 36)
= a(a² + 6a + 36) -6(a² + 6a + 36)
= a³ + 6a² + 36a
<u> - 6a² - 36a - 218</u>
= a³ + 0a² + 0a - 218
= a³ - 218
