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:
Step-by-step explanation:
Given Initial deposit = $125
If each moth $55 is being deposit, the balance each month will form an AP as shown;
125, 180, 235...
The nth term of the AP is expressed as;
y = a + (x-1)d
a is the first term = 125
d is the common difference = 180- 125 = 235-180 = 55
Substitute
y = 125 + (x-1)55
y =125+55x-55
y = 70+55x
y = 55x + 70
