Second one, and can I have brainelist,please, and thanks
We are given with:
Average height of plants to be at least 73 inches
Three plants with heights of
70, 71, 72
The inequality that can be used to determine the possible heights of the fourth plant is:
(70 + 71 + 72 + x) / 4 ≥ 73
Solving for x
x ≥ 79
<h3>
Answer:</h3>
The expression is undefined when x=3 or -3
<h3>
Solution:</h3>
- An expression is undefined when it's divided by 0.
- In order to make the denominator equal 0, we need to subtract 9-9.
- Notice that x is squared.
- So x times itself should equal 9. What number is it?
- That's right, 3.
- So we have
- 9-(3)^2=9-9=0
- There's also another solution: x=-3 (-3•(-3)=9
Hope it helps.

Answer: $100,000
Step-by-step explanation:
Let P be the amount he invested in 5% profit .
then 250,000-P be the amount he invested in 10% profit .
The total profit he earns at 5% =5% of P
⇒The total profit he earns at 5 %=0.05P
Now, The total profit he earns at 10% =10% of (250,000-P)
⇒The total profit he earns at 10%=
According to the question,
Thus, the money he invest in the company that made 5%= $100,000
