Answer:
D. (x - 2)(x + 2)
Step-by-step explanation:
Look at the graph, when y = 0, x = - 2 and x = 2, vertex = -4
OK so x = -2 means x + 2 = 0
and x = 2, means x - 2 = 0
So
answer :D. (x - 2)(x + 2)
Answer:
9/10 or 0.45 in decimal form
Step-by-step explanation:
The answer is x=7 cuz 17x+1=120
Here is the correct order of the step:
Identify: Anna's time is the unknown
Strategize : let x = Anna's time
Set up : 7(40) = x(50)
Solve: x = 5.6
Check: 7(40) = 5.6(50)
<h3>What is Anna's time?</h3>
The first step is to determine the distance Allen travelled:
Distance = average speed x time
40 x 7 = 280 miles
The second step is to determine the time it took Anna to travel 280 miles.
Time = distance / average speed
280 / 50 = 5.6 hours

Answer:
29
Step-by-step explanation:
-18 (Negative Eighteen) = A
29 (Positive Twenty Nine) = B
11 (Positive Eleven) = C
First, make A positive, and add C to it. You get B.
Now here is the equation:
-18 + (18 + 11)
-18 + (29)
11
