The sum (addition) of -2 and 3 times (3 ·) a number (n)
-2 + 3n
50 degrees because 50+50= 100 +80 = 180 and there is 180 degrees in a triangle
Answer:
Step-by-step explanation:
Factor the sum of cubes
a³ + b³ = (a+b)(a² - ab +b²)
= 2a² - 2ab + 2b²
a³ + b³ + 6ab = 2a² + 4ab + 2b²
= 2(a² + 2ab +b²)
= 2(a+b)²
= 8
