The distributive property: a(b + c) = ab + ac
(x - 3)(4x + 2) = (x)(4x + 2) + (-3)(4x + 2)
= (x)(4x) + (x)(2) + (-3)(4x) + (-3)(2) = 4x² + 2x - 12x - 6
<h3>= 4x² - 10x - 6</h3>
8x - (5x + 4) ≥ -31
8x -5x - 4 ≥ -31
3x ≥ -31 + 4
3x ≥ -27
x ≥ - 9
Answer: a numbe line with a circle on - 9 and shading to the left.
Because that drawing represents the number that are less or equel than -9 and the answer is the numbers greater or equal than -9.

Answer:
as always, the rate of change is ∆y/∆x. In this case, that's
(127-95)/(3-1) = 16

Answer:
3 days
Step-by-step explanation:
Kali runs 10 laps around a track each day, and each lap is 400 meters. So, the first step would be:
10 • 400 = 4,000
That means Kali runs 4,000 meters each day.
Now, there are 1,000 meters in 1 kilometer. This means he runs 4 kilometers each day, and we're trying to get to 12 kilometers.
The final step is to divide. 12/4 = 3
So, it would take 3 days for him to run a total of 12 kilometers.
