Answer:
e < 9
Step-by-step explanation:
e/3 + 2 < 5
-2 -2
e/3 < 3
Multiply both sides by 3 to get e by itself
e < 3 × 3
e < 9
Answer:
26 miles
Step-by-step explanation:
Given: 24 miles drive to north.
10 miles drive to east.
Driving pattern form a right angle triangle, which has three leg including straight line distance from starting point (hypotenous).
Now, using Pythogorean theoram to find straight line distance from starting point.
h²= a²+b²
Where, h is hypotenous
a is opposite leg
b is adjacent leg.
⇒h²= 
⇒
⇒
Taking square root on both side, remember; √a²= ±a
⇒
∴ 
Ignoring -26 as distance cannot be negative.
Hence, 26 miles is the straight line distance from starting point.
Perimeter means finding the total area of the outside of the triange (so the sum of all sides).
