Answer:
(3x - 7y)(3x + 7y)
Step-by-step explanation:
9x² - 49y² ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
here 9x² = (3x)² ⇒ a = 3x and 49y² = (7y) ⇒ b = 7y
9x² - 49y²
= (3x)² - (7y)² = (3x - 7y)(3x + 7y)
Answer:
The function f(x) will equal zero when x = 2/17.
Step-by-step explanation:
Combine like terms and set the resulting expression equal to zero. We get:
f(x) = 34x - 2 = 0
Adding 2 to each 34x - 2 and 0, we get 34x = 2. Solving this for x yields
x = 2/17
The function f(x) will equal zero when x = 2/17.

Step-by-step explanation:
there are three people. a grandfather, a father, and a son. the grandfather is the father of the father, and the father is the father of the son (if that makes any sense). the father is the son of the grandfather, and son is the son of the father. so technically while there are 2 sons and 2 fathers, there are still three people. :)
