Answer:he will use all his money
Step-by-step explanation: 10 times 24=240
Given, (9x - 4)(9x + 4) = ax² - b
From algebraic identities:
We know, (a + b)(a - b) = a² - b²
Now, 81x² + 36x - 36x - 16 = ax² - b
81x² - 16 = axis² - b
So ax² = 81x²
a = 81
-b = -16
b = 16
Solution
Therefore, the value of a is 81.

If you move over a negative multiplication or devision
you need to rotate the > sign to <
-x > 5, x < 5
Sometimes you sign contract in wich you need make a deal to supply atleast 1000 products, so if you make a formula for your production it would look something like: 5x + 10 > 1000
Answer:
2.5 hours
Step-by-step explanation:
To get the hourly speed, we need to divide 430 by 5.
This means that the train is going at a speed of 86 miles/hour.
Since we need to find the hour, we need to divide 215 miles by 86 miles/hour.
We can use the keep change flip to do 
This would give us 2.5 hours.
