6v(2v+3)=6v\cdot2v+6v\cdot3=12v^2+18v



6v\cdot2v=6\cdot2\cdot v\cdot v=12\cdot v^2=12v^2\\\\6v\cdot3=6\cdot3\cdot v=18\cdot v=18v

6v(2v+3)
1) 6v*2v=12v^2
2) 6v*3=18v
3)put them together like this: 12v^2+18v this is your answer. If the sign had been a minus in front of the 3 your answer would have been a subtraction equation.

When f(x) = x2+9 and g(x) = x-9, find f(x)-g(x).
ohaa [14]

Answer:

\huge{ \boxed{ \sf{ {x}^{2}  - x + 18}}}

Step-by-step explanation:

\underline{ \text{Given}}:

\sf{f(x) =  {x}^{2} +9  \: and \:  g(x) = x-9}

\underline{ \text{To \: find}} :  \sf{ \: f(x) \:  -  \: g(x)}

Put the values:

\mapsto{ \sf{ {x}^{2}  + 9 - ( x  - 9)}}

While subtracting , sign of each term of the second expression changes.

\mapsto{ \sf{ {x}^{2}  + 9 - x + 9}}

Add the numbers : 9 and 9

\mapsto{ \boxed{ \sf{{x}^{2}  - x + 18}}}

Hope I helped!

Best regards! :D

4-5y&lt;14<br> Values that make it true?
Helga [31]

Answer:

any number greater than -2

Step-by-step explanation:

4 - 5y < 14

step 1: subtract 4 from each side "

4 - 4 cancels out

14 - 4 = 10

now we have -5y < 10

step 2: divide each side by -5

-5y/-5=y

10/-5=-2

( IMPORTANT NOTE: WE MUST FLIP THE INEQUALITY SIGN IF WE DIVIDE BY A NEGATIVE NUMBER)

We would be left with y > -2
