Answer 1
Answer:

Answer:

25.04\,* \,3.005=75.24520

Step-by-step explanation:

Multiplication refers to repeated addition of same number .

For example 2 * 3 means 3 is added 2 times or we can say 2 is added 3 times .

Here, we need to find product of 25.04 and 3.005 .

To solve : 25.04\,* \,3.005

First, we will solve 2504* 3005

2505* 3005=7524520

Now number 25.04 has 2 decimal places and 3.005 has 3 decimal places, so  will shift decimal  2 + 3 = 5 places towards left of number 7524520 .

So, 25.04\,* \,3.005=75.24520

D. Is a difference of squares: (y + 5)2

Answers

Answer:

Option: C is the correct answer.

C.   Is a difference of squares: (y + 5)(y − 5).

Step-by-step explanation:

We are given a polynomial expression in terms of the variable y as follows:

                        y^2-25

Now this expression could also be written as:

y^2-25=y^2-5^2

This means that the expression is a difference of squares.

Also, we know that:

a^2-b^2=(a+b)(a-b)

Here,

a=y\ and\ b=5

Hence,

y^2-25=(y+5)(y-5)
the answer is C
    y² - 25
= y² - 5²
 =  (y + 5)(y - 5) which is a difference of two squares
