Answer:
x^2-8x+16
Step-by-step explanation:
(x-4)^2
x^2-4x-4x+16
x^2-8x+16
So we would want to isolate x. Start by multiplying both sides by -3. Since we are multiplying negative number, we flip the sign.
So that would be x ≥12. That means x should be greater than or equal to 12.
So now it's easy to answer.
C, D, E would be the answer.
Answer:
The actual length of Salamander Trail is 28 miles
Step-by-step explanation:
Here, we want to calculate the actual length of salamander trail.
From the question, we are told that a a distance of 3cm on the map B is 24 miles in the park
So now, we have length of 3.5 cm and we want to calculate what is the actual length in miles
From the question on map B;
3 cm = 24 miles
so
3.5 cm = x miles
x * 3 = 24 * 3.5
x = (24 * 3.5)/3
x = 8 * 3.5 = 28 miles
Answer:
-2, 5.5
The best way to do this is to draw a graph.
