Answer:
10x
Step-by-step explanation:
By definition
![(f\codt g)(x)=f(x)\cdot g(x)](https://tex.z-dn.net/?f=%28f%5Ccodt%20g%29%28x%29%3Df%28x%29%5Ccdot%20g%28x%29)
So we just need to multiply the two functions
![(f\cdot g)(x)= f(x)\cdot g(x)\\=\sqrt{2x}\cdot \sqrt{50x}\\=\sqrt{(2x)\cdot (50x)}=\sqrt{100x^2}\\=10\sqrt{x^2}\\=10x \text{ since x is non negative}](https://tex.z-dn.net/?f=%28f%5Ccdot%20g%29%28x%29%3D%20f%28x%29%5Ccdot%20g%28x%29%5C%5C%3D%5Csqrt%7B2x%7D%5Ccdot%20%5Csqrt%7B50x%7D%5C%5C%3D%5Csqrt%7B%282x%29%5Ccdot%20%2850x%29%7D%3D%5Csqrt%7B100x%5E2%7D%5C%5C%3D10%5Csqrt%7Bx%5E2%7D%5C%5C%3D10x%20%5Ctext%7B%20since%20x%20is%20non%20negative%7D)

Answer:
The value of x is 3
Step-by-step explanation:
∵ Quadrilateral ABCD is congruent to quadrilateral JKLM
∴ AB = JK and BC = KL
∴ CD = LM and AD = JM
∵ BC = 8x + 7
∵ KL = 31
∵ BC = KL
→ Equate their right sides
∴ 8x + 7 = 31
→ Subtract 7 from both sides
∵ 8x + 7 - 7 = 31 - 7
∴ 8x = 24
→ Divide both sides by 8 to find x
∴
= ![\frac{24}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B24%7D%7B8%7D)
∴ x = 3
∴ The value of x is 3
