49 would be the answer I hope it helps
Perimeter of a square = 4L
4L = (8x+12)ft
L= (2x+3)ft
We know that: <span>3(x-1)^2-162=0
or (x-1)</span>²= 162:3
and (x-1)²= 54
we <span>take the square root of both sides
* x-1=</span>√54= 3√6 or x=1+3√6
* x-1= -<span>√54= -3√6 or x=1-3√6
This equation has 2 solutions</span>
Answer:
B
Step-by-step explanation:
we have to find for what value of x the graph exists.
1) start to see on the left
- the graph ”hasn’t a start“ so it continues to go until -oo
2) notice that the graph stops when x = 0
3) match the two informations
x≤0
