- a • [- b] = c
[a] • [- b] = - c or [-a] • [b] = - c (either one is fine)
[- c] / - b = a
[- c] / [b] = - a
According to google A. Would be 2.375 or as a fraction it would be 2 3/8
I know its a long problem but i have to shiw how i got my answer.
Answer:
n x p = c
Step-by-step explanation:
n is the amount of pens so we time it by the cost of 1 pen which is p and the final answer is c as the cost of all the pen.
Combine like terms
-7y² + 6y² - 2y² = -3y²
4y + (-5y) - (-9y) = 4y - 5y + 9y = 8y
9 + 9 - (-2) = 9 + 9 + 2 = 20
-3y² + 8y + 20 is your answer
hope this helps
