Answer:
(x + 2)(x² - 2x + 4)
Step-by-step explanation:
x³ + 8 ← is a sum of cubes, which factors in general as
• a³ + b³ = (a + b)(a² - ab + b²)
x³ = (x)³ ⇒ a = x and 8 = 2³ ⇒ b = 2
x³ + 8 = (x + 2)(x² - 2x + 4) ← in factored form
Answer:
B. What is the area of regular polygon
Answer:
c. 6
Step-by-step explanation:
19z-7 - ( 5z-9 + <span>8z+3)
= 19z - 7 - (13z - 6)
= 19z - 7 - 13z + 6
= 6z - 1
answer
remaining side = </span> 6z - 1
