Answer:
![goh(x)=x^3+12x^2+49x+68](https://tex.z-dn.net/?f=goh%28x%29%3Dx%5E3%2B12x%5E2%2B49x%2B68)
Step-by-step explanation:
![g(x) = x^3+x](https://tex.z-dn.net/?f=g%28x%29%20%3D%20x%5E3%2Bx)
![h(x)=x+4](https://tex.z-dn.net/?f=h%28x%29%3Dx%2B4)
We have to find
![goh(x)](https://tex.z-dn.net/?f=goh%28x%29)
![goh(x) = g(h(x))=g(x+4)](https://tex.z-dn.net/?f=goh%28x%29%20%3D%20g%28h%28x%29%29%3Dg%28x%2B4%29)
If ![g(x) = x^3+x](https://tex.z-dn.net/?f=g%28x%29%20%3D%20x%5E3%2Bx)
![g(x+4) = (x+4)^3+(x+4)](https://tex.z-dn.net/?f=g%28x%2B4%29%20%3D%20%28x%2B4%29%5E3%2B%28x%2B4%29)
=![x^3+12x^2+49x+68](https://tex.z-dn.net/?f=%20x%5E3%2B12x%5E2%2B49x%2B68)
Hence our answer is
![goh(x)=x^3+12x^2+49x+68](https://tex.z-dn.net/?f=goh%28x%29%3Dx%5E3%2B12x%5E2%2B49x%2B68)
To find the area of a rhombus using diagonals, you must multiple the diagonals and divide then by 2. In this case 37 * 20 is 740. 740/2 is 370. 370 is your answer
