Here hope this help the solution is X= -2 and y=9
Statistical questions: A, C, E, because they all talk about students, where B and D talk about adults and people in general. Frank just wants to know about students.
First we calculate the volume of the foundation:
Volume (V) = 20 ft * 12 ft * 4 in (1 ft / 12 in)
V = 80 ft^3
Since the cost is in cubic yard (yard^3) so convert:
V = 80 ft^3 * (1 yard^3 / 27 ft^3) = 2.963 yard^3
So the total cost is:
cost = ($125 / yard^3) * 2.963 yard^3
<span>cost = $370.37</span>
It could sometimes be proportional. The reasoning here is that if all the items have different prices it won't be, however if the items you are ordering all have the same price they will be!
Take a look at all 3 expressions: numbers, terms, and exponents.
4, 8, and 6 all have a GCF of 2.
y^5, y^3, and y^2 have a GCF of y^2.
Therefore, the GCF is 2y^2. Removing it gets you:
2y^2(2y^3 + 4y - 3)
