Plug in x = 12 and y = -5 into the given equation:-
3(12) - 3(-5) = 36 + 15 = 51 Not 21
So (12,-5) is not a solution.
Answer:
5x² - 20x
Step-by-step explanation:
multiply each term in the parenthesis by the 5x outside
5x(x - 4)
= (5x × x ) + (5x × - 4 )
= 5x² + (- 20x) = 5x² - 20x
The product of 5 and n is written as
.
Two less than this product is
