I think this is factorials
so an example would b....... 1*2*3*4*5.... ect
hope this helps
The answer is B. (2x + 5)(x + 1)You could answer this by expanding each answer until you found one that matched 2x^2 + 7x + 5, but I will only show how the answer expands:
2x × x = 2x^2
5 × x = 5x
2x × 1 = 2x
5 × 1 = 5
So in total those brackets expand to 2x^2 + 7x + 5. I hope this helps!
The surface area of the right triangular prism is 270 sq ft
<h3>Total surface ara of the prism</h3>
The total surface area of the prism is the sum of all the area of its faces
For the two triangles
A = 2(0.5bh)
A = bh
A = 7 * 12 = 84 sq.ft
For the two rectangles
A = 2lw
A = 2(6*12)
A = 2 * 72 = 144 sq.ft
For the third triangle;
Area 6ft * 7ft
Area = 42 sq.feet
Taking the sum of the areas
TSA = 84 + 144 + 42
TSA = 270 sq ft
Hence the surface area of the right triangular prism is 270 sq ft

Answer:48V/10
Step-by-step explanation:
I got it right from Khan Academy
Answer:
The division will be represented as:
![\frac{18x^{2}-3x+4}{6x+5}=(3x-3)+\frac{19}{6x+5}](https://tex.z-dn.net/?f=%5Cfrac%7B18x%5E%7B2%7D-3x%2B4%7D%7B6x%2B5%7D%3D%283x-3%29%2B%5Cfrac%7B19%7D%7B6x%2B5%7D)
Step-by-step explanation:
1) Let's find a number with a variable that multiplied by 6x gives as 18x². It will be 3x, because (6x+5)3x=18x²+15x.
Now, let's subtstract:
![(18x^{2}-3x+4)-(18x^{2}+15x)=-18x+4](https://tex.z-dn.net/?f=%2818x%5E%7B2%7D-3x%2B4%29-%2818x%5E%7B2%7D%2B15x%29%3D-18x%2B4)
2) Let's find a number with a variable that multiplied by 6x gives as -18x. It will be -3, because (6x+5)(-3)=-18x-15.
Now, let's subtstract:
Therefore, the division will be represented as:
![\frac{18x^{2}-3x+4}{6x+5}=(3x-3)+\frac{19}{6x+5}](https://tex.z-dn.net/?f=%5Cfrac%7B18x%5E%7B2%7D-3x%2B4%7D%7B6x%2B5%7D%3D%283x-3%29%2B%5Cfrac%7B19%7D%7B6x%2B5%7D)
I hope it helps you!
