5(x + 3) + 9 = 3 (x - 2) + 6
5x + 15 + 9 = 3x - 6 + 6
5x + 24 = 3x
5x - 3x = -24
2x = -24
x = -24/2
x = - 12
Answer:
3/-2
Step-by-step explanation:
The negative sign applies for the whole fraction
Exactly what was your answer for a
Pythagorean theorem: a^2 + b^2 = c^2
a^2 + 16^2 = 65^2
a^2 + 256 = 4225
a^2 = 3969
a = 63
Perimeter: add all sides
63 + 16 + 65 = 144
Solution: 144 feet
It should be the third one down.
