Step 1 should be
Bring the constant to the other side and divide the whole equation with 6 resulting to
x2 + 4x = -7/6
Step 3 should be
Complete the square by dividing the coefficient of x by 2, squaring it and adding the result to both sides of the equation.
x2 + 4x + 4 = -7/6 + 4
Step 4 should be
Factor the quadratic equation and simplify
(x+2)2 = -17/6
Step should be
Get the square root of booth sides and solve for the values of x
x+2 = +-√(102) / 6
So,
x = -2 + √(102) / 6 and x = -2 - <span>√(102) /3

X = 11
angle LKM = angle KLM = angle LMK because it is an equilateral triangle
180/3 = 60
60=3x-27
60-27=3x
33=3x
x=11
Its B
-130 + 240= 110
110- 56 = 54
So.. 54 is your answer
Answer:
The perimeter of the larger hexagon is 54 yards
Step-by-step explanation:
The ratio is 5/9
So the ratio of the perimeters is going to be the same
5 30
--------- = ----------
9 P2
5 * P2 = 30 * 9
5 * P2 = 270
Divide each side by 5
5 P2 = 270/5
P2 =54
The perimeter of the larger hexagon is 54 yards
