The volume of the rectangular prism below is 30x3 + 35x2 + 10x factor to find the possible expressions for length,width and heig
juin [17]
30x³ + 35x² + 10x factorised is 5x(2x + 1)(3x +2). To find this, you first want to take out a common factor to be left with a quadratic equation. In this case, we can factor out 5x to be left with 6x² + 7x + 2.

Now we can factorise 6x² + 7x + 2 by finding factors of 6 that add together to make 7 when one of them is multiplied by 2. These are 3 and 2, which is how we end up with (2x + 1) and (3x + 2). Let me know if you would like me to go more indepth about how I found this.

Then you just put these with the 5x and you get 5x(2x + 1)(3x + 2), which are possible expressions for the length, width, and height.
I hope this helps!

F(x) = x(x - 1)<br> g(x) = 3x<br> Find (f *g)(6)
olchik [2.2K]

Hey there!

\large\boxed{540}

(f * g)(6) is equal to x(x-1) × 3x.

So, let's plug in 6 for x.

(f * g)(6) = 6(6-1) × 3(6)

Subtract inside parenthesis.

(f * g)(6) = 6(5) × 3(6)

Multiply.

(f * g)(6) = 30 × 18

Multiply again.

(f * g)(6) = 540

Hope this helps!

Does anyone know this one

B. 12

First you pick a location and then a direction.

I decided to start from the left and then go right. Then set up my ratio as

2/3=8/x

Then you cross multiply.

2*x=2x. 8*3=24

2x=24

Divide 2 on both sides

X=12
