Answer:

We have the equation A*C = A

Now, as both sides of the equality are the same thing, we can do the same operation to both sides and the equality will remain true.

We can divide both sides by A and get:

(A*C)/A = A/A

C = 1

So here we finded the value of A.

If A and C are matrices, then C is the identity matrix.

Answer:

$\large \boxed{\sf \ \ -3x^3-x^2+x+18 \ \ }$

Step-by-step explanation:

Hello, please consider the following.

$(f-g)(x)=f(x)-g(x)=x^2-3x+9-(3x^3+2x^2-4x-9)\\\\=x^2-3x+9-3x^3-2x^2+4x+9\\\\=\boxed{-3x^3-x^2+x+18}$

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

What is the value of X

alexdok [17]

Answer:

$x=12$

Step-by-step explanation:

We have been given a graph of similar triangles. We are asked to find the value of x.

Since we know that corresponding sides of similar triangles are always in same proportion, so we will use proportions to find the length of x.

$\frac{3}{x+3}=\frac{4}{16+4}$

$\frac{3}{x+3}=\frac{4}{20}$

Upon cross multiplying our equation we will get,

$4*(x+3)=3(20)$

Upon distributing 4 we will get,

$4x+12=60$

Let us subtract 12 from both sides of our equation.

$4x+12-12=60-12$

$4x=48$

Upon dividing both sides of our equation by 4 we will get,

$\frac{4x}{4}=\frac{48}{4}$

$x=12$

Therefore, the value of x will be 12.
