Mathematics
1 answer:
Whitepunk [10]2 years ago
4 0

Answer:

Step-by-step explanation:

These binomials make up the difference of squares.

3x * 3x = 9x^2

3x * 5 = 15x

-5 * 3x = - 15x

-5 * 5 = - 25

Notice the 2nd and 3rd terms. They are equal except that one is plus and the other minus. That means they cancel. You are left with

9x^2 - 25

What is the value of s in the equation
galben [10]
The answer is B. 16  because you multiply 4 with 2s and -1 so the new equation will be 8s-4=7s+12 and you have to subtract the variable 7s to 8s the equation will be 1s-4=12 and add 4 to 12 and it gives you 16 and just divide 16 and one and you answer should be 16. :)
