Answer:

third one

Step-by-step explanation:

the third one should be the answer

step 4 came out becoz of taking the common factor(x+1) and combining x2 and (-16)

Step 5 came out becoz of the theory of (a^2-b^2) = (a+b)(a-b)

ps 16 here is equal to 4^2

Suppose that the functions and are defined for all real numbers as follows. r(x)=3x^(2) s(x)=2x write the expressions for (r-s)(

nirvana33 [79]

The expression for (r-s)(x) is found by subtracting s from r. That difference is $3 x^{2} -2x$ . The expression for (r+s)(x) is found by adding them, which is $3 x^{2} +2x$ . Now we are told to evaluate (r*s)(x) which means they want us to multiply those and state the "new" expression that results. $(3 x^{2} )(2x)=6x^3$ . There you go!

Convert to scientific notation

andreev551 [17]

Answer:

8.245*10^6

Step-by-step explanation:

scientific notation is known as c*10^n

c : any number from 1-10

n : the power of base 10

the number in our case between 1 and 10 is 8.245

but then we want to move the decimal 6 spaces to the right, so we multiply that by 10^6
