Algebra 2 Solve: f(x)=x^2-9

1 answer:

7 0

This problem is a difference of squares. So to solve this you want to factor it out so you get two numbers that multiple to -9 and add to 0. That would be -3 and 3

f(x)=(x-3)(x+3)

So your solution when you set f(x) to 0 would be -3 and 3.

Answer:

The bottom question is wrong. You have to multiply 8 to get the amount earned. But the rest is correct.

12.5 x 8 = 100

18.75 x 8 = 150

25 x 8 = 200

If there are 37 figures and there are six people how many will each person get

Elis [28]

Answer:

It depends.

Step-by-step explanation:

If we're able to brake the figures, then each person will get six and one sixth of a figure

$37 \div 6 = 6 \frac{1}{6}$

But if we can't break them, then each person will get six figures with one remaining ungiven.

$37 \div 6 = 6 \: (1)$
