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
Answer:
y = -2x + 4
Step-by-step explanation:
y = mx + b
m ---> slope
b ----> y-intercept
y = -2x + 4
Answer:

Step-by-step explanation:
all you have to do is divide 20 into 300
F - because you must move the decimal place 9 spaces to the left in order to have only a single digit in front of the decimal place. (There can never be more than one otherwise it is no longer scientific notation.
Answer:
x=16
Step-by-step explanation:
We are given that
we have to solve this equation for x
in order to do that we need to isolate x first
hence
subtracting 11 from both sides we get
Now we square on both sides we get
hence x =16
