Good evening
Answer:
Step-by-step explanation:
g(x) = -20
⇔
3x-1 = -20
⇔
3x = -20 + 1
⇔
3x = -19
⇔
x = -19/3

N + 3n+4 + 4n-1 = 59
8n + 3 = 59
8n = 56
n = 7
The sides are 7, 3(7)+4, 4(7)-1
The three side lenght are 7, 25, 27
So to find the answer u must multiply 20 x 5= 100
Around 20.44
If you use long division you try to fit 17 into 347 as many times as you can then move the remainder down and keep dividing
