Answer:
D. 7.8
Step-by-step explanation:
Distance formula: 
Substituting (-2 - 3)² + (-5 - 1)²
Distance = 
Distance = 
Distance = 7.8
The balloons of each color that Marty inflated are:
- Marty
- inflate
- red 271
- ballons
- Marty
- inflate
- red 380
- ballons
This is further explained below.
<h3>How many balloons of each color did Marty inflate?</h3>
Generally, the equation for the statement is mathematically given as
w= r+225
w - 225 = r
Therefore
w - 116 = b
Where
r + w + b = 1147
(w - 225 )+w +( w - 116)=1147
3w = 1147 + 341
w = 496
In conclusion, For Red
w - 225 = r
496 - 225 = r
r=271
Marty inflate red 271 ballons
For blue
w - 116 = b
496 - 116 =380
b=380
Marty inflate red 380 ballons

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>
