Answer:
x = 4 ± 
Step-by-step explanation:
Given
(x - 12)(x + 4) = 9 ← expand the left side using FOIL
x² - 8x - 48 = 9 ( ad 48 to both sides )
x² - 8x = 57
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 4)x + 16 = 57 + 16
(x - 4)² = 73 ( take the square root of both sides )
x - 4 = ±
( add 4 to both sides )
x = 4 ± 
You would have about 3472 Hours
.18\8=1.44 for 8 hour
5000/1.44=3472
Hope this helps :)
Answer:
△ABC∼△EDF
Step-by-step explanation:
4(8x-2)
Distribute the 4
So it should be 32x-8
Hope it helps
K here you go!!! So, this is the slope formula: m=(y_2-y_1)/(x_2-x_1). We can input the example coordinates given to create: (-4-3)/(-4-2). Then, I can simplify to make -7/-6 or 7/6. You can make it improper or not, up to you or the question. Also, in the part where I inputting the numbers into the formula, it doesn't matter what y-coordinate value or x-coordinate value you use. The slope won't change.
