The volume of each individual brick is 72 cubic inches.
<h3>
How to get the volume of each brick?</h3>
The volume of a rectangular prism of height H, width W, and length L is given by:
V = L*H*W
In this case we have:
- L = 8in
- W = 4in
- H = 2.25 in
Then, replacing these in the volume equation, we get:
V = (8 in)*(4 in)*(2.25 in) = 72in³
So the correct option is the second one.

The answer to this question -9
To find each term, you have to multiply the number before it by [tex]\frac{3}{2}[\tex] so the answer would be
<span>[tex]\frac{3}{2}(n - 1)[\tex]</span>
Answer: 40 degrees
Step-by-step explanation:
The 3 angles of a triangle must add up to 180 degrees.
Let's say this is triangle ABC and angle A has a measure of 100 degrees.
That leaves 80 degrees to be split evenly between angles B and C.
80/2 = 40, so angles B and C must each be 40 degrees.
The value of y varies directly as the square of x and y = -12 when x = 2 then the value of y when x = -4 exists y = 24.
<h3>What is meant by direct variation?</h3>
When two variable quantities contain a constant ratio, their relationship exists comprehended a direct variation. It exists said that one variable varies directly as the other. The formula for direct variation is y = kx, where k exists the constant of variation.
The constant value (often written k) relating amounts that rise or fall uniformly together. It exists the ratio of the amounts y and x:
k = y/x.
Put another way: y = kx.
Accordingly, the equation has the form y = kx, where k may be any number.
Substituting y = -12 when x = 2, we get
-12 = k × 2
simplifying the above equation, we get
⇒ k = -6
Therefore, the required equation exists y = -6x.
The value of y when x = -4 is y = -6 × -4 = 24.
