(1 Point)
x^2– 25

Let's factor x2−25

x2−25

The middle number is 0 and the last number is -25.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get 0

Multiply together to get -25

Can you think of the two numbers?

Try 5 and -5:

5+-5 = 0

5*-5 = -25

Fill in the blanks in

(x+_)(x+_)

with 5 and -5 to get...

(x+5)(x-5)

(x+5)(x−5)

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
