Answer:
|-2| + |5|
Step-by-step explanation:
Dennis walks from (–5, –2) to (–5, 5) on the map.
Point on the format (x,y). On the x-coordinate, he stayed at the same position, x = -5, so it does not enter the distance calculation.
On the y-coordinate, he went from -2 to 5, so the distance is of:
![d = 5 - (-2) = 5 + 2 = |5| + |2| = |5| + |-2| = 7](https://tex.z-dn.net/?f=d%20%3D%205%20-%20%28-2%29%20%3D%205%20%2B%202%20%3D%20%7C5%7C%20%2B%20%7C2%7C%20%3D%20%7C5%7C%20%2B%20%7C-2%7C%20%3D%207)
So the correct option is |-2| + |5|
Answer:
Step-by-step explanation:
<em>Note. It should read 3/4 of an inch.</em>
- 3/4 in = 3 miles
- x in = 25 miles
<u>Cross multiply and solve for x:</u>
I think the third option is correct.
Answer:
area = 49 ft²
Step-by-step explanation:
The area (A) of a triangle is calculated using the formula
A =
bh ( b is the base length and h the height )
here b = 14 and h = 7
A =
× 14 × 7 = 7 × 7 = 49 ft²
