(X + 4)(X^2 - 1) = x^3 + 4x^2 - x - 4
Answer:
I think its number 4
Step-by-step explanation:
but im not sure
Answer: You would just use the regular steps going through the process of distribution in mathematics.
Step-by-step explanation: The equivalent expression would be 4(x)+4(-2)+4(y)
Y=|x| +3
Y=-|x+2| -1
Y=3|x-4| - 5

First, determine the area of the driveway by multiplying its length by its width, so
a = 10 * 150.5 = 1505 ft^2
Now convert from ft^2 to yd^2 by dividing by 9.
1505 ft^2 / 9 ft^2/yd^2 = 167.222 yd^2
Finally, multiply by the cost per sq yd
167.222 * 25 = 4180.56</span>
