Answer:
a 3 + b 3 = (a + b) (a 2 − a b + b 2 ). Substituting a = x and b = 3 into the formula yields: x 3 + 27 = (x + 3) (x 2 − 3 x + 9).
Step-by-step explanation:
Answer:
30
Step-by-step explanation:
Substitue 3 for every x in the equation
10(3)-(3*3)(2*3)+(3)^2(2*3)
Multiply
30-(9)(6)+9(6)
30-54+54=30
5 years because when you divide 90 by 18 to get how many years it takes the tree to grow to 90 inches tall, you get 5.
5 1/6 divided by 2 5/12 is 2 4/29 so it is true
3 + (w² + x²) = 32 is the correct answer
