1) Remove parentheses.

2) Regroup terms.

none of the above
Step-by-step explanation:
- 36x²-4x+16 = (6x)²- 2*2*x+ 4² this isn't a perfect square trinomial
- 16x²-8x+36 = (4x)² - 2*4*x+6² this isn't a perfect square trinomial
- 25x²+9x+4= (5x)²+2* 9/2 *x+ 2² this isn't a perfect trinomial
- 4x²+20x+25 = (2x)² + 5*4*x+5² this isn't a perfect trinomial square
A, C, and E.
you can check them by putting into y=mx+b form. if m is negative then as domain increases range decreases.

Answer:
x =9/4
Step-by-step explanation:
log3(4x) = 2
Raise each side to the base of 3
3^ log3(4x) = 3^2
We know that 3log3 is 1
4x = 9
Divide each side by 4
4x/4 = 9/4
x = 9/4
