X^{2} -25=0 Please help meeee

-BARSIC- [3]

Answer:

$x=5,x=-5$

Step-by-step explanation:

$x^2-25=0$

Add 25 to both sides:

$x^2-25+25=0+25$

$x^2=25$

Square root both sides:

$x=\sqrt{25},\:x=-\sqrt{25}$ (Since a negative number multiplied by itself gives positive, there are two answers.)

$x=5,x=-5$

Tems11 [23]

Answer:

50 legs

Step-by-step explanation:

We know that a dog has 4 legs, a cat has 4 legs, a giraffe has 4 legs, a duck has 2 legs, and a chicken has 2 legs. So, we want to calculate $2(4)+4(4)+1(4)+5(4)+1(2)+3(2)$ , right?

Wrong! It's a trick question! The chickens aren't on the floor, so they don't count. So, we really want $2(4)+4(4)+1(4)+5(4)+1(2)$ .

We multiply it out to get $8+16+4+20+2$ .

We add these up to get $50$ .

So, our answer is $\boxed{50}$ legs.
