Answer:
324
Step-by-step explanation:
Given:

Find:

First, find f(x):

Now,

25x^2 - 64y^2
The first thing you can do is look for a subtraction sign. The word difference implies subtraction, so you can rule out any expressions that add terms. Secondly, you can look for squares. 17x^2 - 23y^2 is a subtraction expression, but 17 and 23 are not squares. However, 25x^2 - 64x^2 is a subtraction expression and its terms are squares. 25 = 5x5, 64 = 8x8. Hope this helps!
3(2x - 1) - 2(3x + 4) = 11x
- Distribute 3 inside the parentheses.
6x - 3 - 2(3x + 4) = 11x
- Distribute 2 inside the parentheses.
6x - 3 - 6x - 8 = 11x
-11 = 11x
<h3>x = -1</h3>
