2(2x-4) because when you multiply 2 x 2x it equals 4x. When you multiply 2 x 4 it equals 8. Leaving you with 4x-8
Answer: 
Step-by-step explanation:
Given: Emelina wrote the equation of a line in point-slope form as shown below.

To write the equation in intercept form, first we multiply 3 inside the bracket values in the right side , we get

Now, subtract 4 from both sides , we get

Hence, Emelina’s equation in slope-intercept form : 
The equation to find out the volume in this case is V=x*x*2x, or V=2x^3. Use this we can get that the volumes would be 16, 54, 128, and 250.
Answer:
D
Step-by-step explanation:
Given
9 - 7x = (4x - 3)² + 5 ← expand the squared factor
9 - 7x = 16x² - 24x + 9 + 5, that is
9 - 7x = 16x² - 24x + 14 ( subtract 9 - 7x from both sides )
0 = 16x² - 17x + 5, that is
16x² - 17x + 5 = 0 ← in standard form → D
