Answer:

x>-2

Step-by-step explanation:

Hi there!

We are given the inequality 7+7(x+4)>21, and we want to solve it

Solving an inequality is a lot like solving an equation; we want to isolate x on one side by itself.

So to start, we'll preform the distributive property on 7(x+4) (multiply x by 7, then multiply 4 by 7 and add those two together).

7+7x+28>21

Now combine like terms.

7x+35>21

Subtract 35 from both sides

7x>-14

Divide both sides by 7

x>-2

Hope this helps!

F(x) = 5x ^ 2 and g(x) = x + 1 find (fg)(x)

Vilka [71]

According to the question given, $f(x)=5x^2,g(x)=x+1$ (fg)(x) is $f(x).g(x)=5x^3+5x^2$

Which is not given in the options.

Step-by-step explanation:

We are given:

$f(x)=5x^2$

$g(x)=x+1$

We need to find (fg)(x)

Solving:

$(fg)(x)=f(x).g(x)\\f(x).g(x)= 5x^2*(x+1)\\f(x).g(x)=5x^3+5x^2$

According to the question given, (fg)(x) is $f(x).g(x)=5x^3+5x^2$

Which is not given in the options.
