Answer:
48 cm^3
Step-by-step explanation:
You can count the cubes in the top layer and make the reasonable assumption that the other two layers have the same number:
(16 cm^3)×3 = 48 cm^3
_____
<em>Alternate solution</em>
The formula for the volume of a rectangular prism is ...
V = LWH
That is, it is the product of the three dimensions.
V = (4 cm)(4 cm)(3 cm)
V = 48 cm^3
Let
x--------> the time in hours
y-------> the distance in miles
we know that
The speed is equal to
in this problem
<u>Equation First Train</u>
<u>Equation Second Train</u>
---------> equation 
Substitute the values of 
and 
in the equation
Solve for x
therefore
<u>the answer is</u>
Answer:
40
Step-by-step explanation:
s = 2;
h = 4
Surface area = 2s² + 4sh
= 2*2² + 4 * 2 * 4
= 2 *4 + 32
= 8 + 32
= 40 sq. units
Question 2: D
Question 1: C
Question 3: B
Question 4: C
I would go with A. while it's true that the function continues to increase the function only begins to increase when it's greater then or equal to -8.
