9x+1 = 2x+15
Subtract 1 from both sides.
9x=2x+14
Subtract 2x from both sides.
7x=+14
Divide 7 on both sides.
x=2
three, twelve, five, and six

ten and a half
Step-by-step explanation:
2×3.5= 7
3×3.5= 10.5
Answer:
The answer is below
Step-by-step explanation:
The distance between two points A(x₁, y₁) and B(x₂, y₂) on the coordinate plane is given by:

Point J is at (-3, 3), point K is at (4, 3) and point L is at (1, -1). Hence:
The distance between K and L = KL = 
The distance between J and L = JL = 
The distance between K and J = JK = 
Therefore, the perimeter of triangle JKL is:
Perimeter = KL + JL + JK = 5 + 4√2 + 7 = 17.66 units
