First, we must know that we can find the volume of a prism using the formula
Volume = length × width × height
Since we are finding the volume of a cube, all the sides will be the same length so we can represent this as Volume = 
.
Now, we can substitute in our values. It does not matter where the numbers go because they are all the same.
7.5 × 7.5 × 7.5 = 421.875
Therefore, the volume of the prism is 421.875 
Answer:
(2, -1)
Step-by-step explanation:
Whenever you reflect a point over the x-axis, the x-coordinate remains the same, but the y-coordinate becomes its additive inverse.
(x, y) ⇒ (x, -y).
(2, 1) ⇒ (2, -1).
Answer:
-36
Step-by-step explanation:
‐13−23= ‐13 + (-23) = -36
Both 13 and 23 have negative sign. So if two numbers have the same sign, we have to add and put the same sign.
Answer:
Option 2 or (B)
Step-by-step explanation:
You always convert the exponent to a fraction if the original is in a square root.
Y (9 + 2y)
= y (9) + y (2y)
= 9y + 2y²
= 2y² + 9y
