The solution of expression (5x² - 4) at x = 3 would be 41.
Given that the expression is,
5x² - 4
Used the concept of substitution method to solve the expression.
Now, substitute x = 3 in the expression,
5x² - 4
5(3)² - 4
5×9 - 4
45 - 4
41
Therefore, the value of the expression is 41.

Answer: 19.723083
Step-by-step explanation:
Answer:
The expression could be written as: 3L-5.
Step-by-step explanation:
We are asked to find an variable equation/ expresssion for the following world problem:
" Five less than three times the length L".
for this we have to firstly take '3' times the length 'L' (i.e. 3L) and then subtract that expression by 5 to make it five less than three times the length 'L' and hence obtain our required expression.
Hence, the expression is represented as: 3L-5
