Answer:
BE = 72 cm
Step-by-step explanation:
(BPT Theorem)
![\frac{20}{5} = \frac{BE}{18} \\](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B5%7D%20%3D%20%5Cfrac%7BBE%7D%7B18%7D%20%5C%5C)
⇒ 4 = ![\frac{BE}{18}](https://tex.z-dn.net/?f=%5Cfrac%7BBE%7D%7B18%7D)
⇒BE = 18 × 4
∴ BE = 72 cm

Answer:
Infinitely many solutions
Step-by-step explanation:
-5.9x - 3.7y = -2.1
5.9x + 3.7y = 2.1
If we add these two equations together, -5.9x cancels out 5.9x, -3.7y cancels out 3.7y, and -2.1 cancels out 2.1.
This leaves us with:
0 = 0
Since this is true, that means there are infinite solutions.
Answer:
3^4
Step-by-step explanation:
Simplifying an expression with expression with exponents:
If they are dividing, we keep the base and subtract the exponents. For example:
![\frac{a^x}{a^y}=a^{x-y}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%5Ex%7D%7Ba%5Ey%7D%3Da%5E%7Bx-y%7D)
