SOLUTION: ``Find the product: (3x + 5)(4x - 1) Which of the following is the equation of a vertical line? x = y y = -4 y = 3x + 2 x = 8 Simplify: (-3a2b5)2 Find (x - 4)2

Question 71331: ``Find the product: (3x + 5)(4x - 1)
Which of the following is the equation of a vertical line?
x = y
y = -4
y = 3x + 2
x = 8
Simplify: (-3a2b5)2
Find (x - 4)2

All work needed to arrive at a correct answer. If it is not a question that requires work, you will need to provide a complete explanation of how you determined the correct answer. (Explanations for those problems not requiring work must demonstrate your understanding of the concept.)

``Find the product: (3x + 5)(4x - 1)
Use FOIL:
F: 3x*4x=12x^2
O: 3x*-1 = -3x
I: 5*4x = 20x
L: 5*-1 = -5
Combine these products to get:
12x^2+17x-5
------------------------

Which of the following is the equation of a vertical line?
x = y
y = -4
y = 3x + 2
x = 8
Answer x=8 ; The graph is the set of points where x=8.
-----------------------
Simplify: (-3a2b5)2
=(-3a^2b^5)(-3a2b^5)
=9a^4b^10
------------
Find (x - 4)^2
=(x-4)(x-4)
Use FOIL to get:
x^2-4x-4x+16
=x^2-8x+16
--------
