Answer:
2nd statement is true
Step-by-step explanation:
Please use " ^ " to denote exponentation: f(x) = 4x^2 + 20x + 25.
Take a look at the second statement. If you'll substitute -2.5 for x, to find f(-2.5), you'll find that the result is 0; Thus, this second statement is true.
It would be 2 divided by 3x minus 2 equals 3 divided by 7, because a fraction is the same as dividing
Using Pythagoras' theorem (a² + b² = c²), the correct answer is:
D. h² = a² - x²
Because a would be the hypotenuse, but h is not, so you have to rearrange the equation.
