The value of the expression, 5x^2 - 4, when x = 2 is: 16.
<h3>What is the the Value of an Expression?</h3>
To find the value of an expression, plug in the given value of the variable and solve by simplifying.
Given the expression, 5x^2 - 4, when x = 2, we would have:
5(2)^2 - 4
5(4) - 4
20 - 4
= 16
Therefore, the value of the expression, 5x^2 - 4, when x = 2 is: 16.

Answer:
10 motorcycles and 30 cars
Step-by-step explanation:
If there are 25 cars and a 5:2 ratio, then 25/5=5, and 5x2=10, then there will be 10 motorcycles.
5:2
Divide by 5 | Multiply by 2
If there are 12 motorcycles, then 12/2=6 and 6x5=30. The ratio is reversed because the translation required is reversed.
2:5
Divide by 2 | Multiply by 5
