Answer:
<em>A ≈ 28.5</em>
Step-by-step explanation:
a, b, c
P = a + b + c
Semiperimeter s = 
A = 
~~~~~~~~~~~~~~~
= 4.3 + 2.89 + 6.81 = 14
s = 14 ÷ 2 = 7
= 
= √14.75901 ≈ 3.84
= 8.59 + 7.58 + 6.81 = 22.98
s = 22.98 ÷ 2 = 11.49
= 
= √609.7343148 ≈ 24.6928
= 3.84 + 24.6928 ≈ <em>28.5</em>
Answer: Because the graphs of the two equations overlap each other
Step-by-step explanation:
Every point on the first line also satisfies the second equation.
This is the same as equivalent fractions
where 1/2 = 2/4 = 3/6 = 4/8
Graphing these on a number line would only show one dot.
