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>
If u check your answer on google ithink u can get
We need to get m by itself. to do that, we divide each side of the equation by -3.3. so, m = 0.333 (repeating decimal).

Answer:
a. 55.5
b. 12
Step-by-step explanation:
a. 94+17=111
180-111=69
2x+69=180
2x=111
x=55.5
b. 180-90=90
5x-7+x+25= 90
6x+18=90
6x=90-18
6x=72
x=12
