The answer would be A. 2744 cubic units
V=a^3=14^3=2744
Answer:
64 cubic inches
Step-by-step explanation:
Answer:
The correct answer is D) x^2 - 2hx + h^2
Step-by-step explanation:
To find this, first expand the equation.
(x - h)^2
(x - h)(x - h)
Now use the FOIL method to multiply.
First me multiply the F - FIRST numbers in each parenthesis.
x * x = x^2
Next multiply the O - OUTER numbers in each parenthesis
x * -h = -xh
Next multiply the I - INNER numbers in each parenthesis
x * -h = -xh
And finally, multiply the L - LAST numbers in each parenthesis
-h * -h = h^2
Now we combine the 4 terms together by adding
x^2 - xh - xh + h^2
x^2 - 2xh + h^2
