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

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

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<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
