Answer:
x = -7 or x = 2/3
Step-by-step explanation:
I'm assuming you meant solve for x when f(x) = 0.
f(x) = 3x(x + 7) - 2(x + 7)
0 = (x + 7)(3x - 2) -- Both terms have a common factor of (x + 7) so we can group them
x + 7 = 0 or 3x - 2 = 0 -- Use ZPP
x = -7 or x = 2/3 -- Solve
Answer:
You add 2 and 3

Answer:

Step-by-step explanation:
If that is a square, then all sides are the same. Therefore, it's a
by
shape. We'll use Pythagorean Theorem to find the diagonal.

Since it's not a fraction, there is no denominator to rationalize. Let me know if you have any other questions!
