Answer:
x = 6
Step-by-step explanation:
Since <A is congruent to <N, they are both an isosceles base angles. ∆CAN is an isosceles ∆.
Therefore, one of the properties of an isosceles ∆ is that two sides are equal, aside the base of the isosceles. This implies that: CN = AC
AC = 18cm
CN = (4x - 6)cm, therefore, we can generate an equation for solve for x as follows,
4x - 6 = 18 (two sides of an isosceles ∆ are congruent)
Add 6 to each side of the equation.
4x - 6 + 6 = 18 + 6
4x = 24
Divide both sides by 4
4x = 24/4
x = 6
Answer: 1.5miles/hour

Answer:
Step-by-step explanation:
4(x+5) = 9x + 4x - 34
distributive:
4x + 20 = 9x + 4x - 34
combine
4x + 20 = 13x - 34
subtraction
20 = 9x - 34
addition
54 = 9x
division
6 = x
Answer: The correct answer is D
Step-by-step explanation: If you were to scale this up to the actual size, the planets would be so close that each planet would collide with each other because the gravity would interfere to much. If this were accurate, you and me both would not be alive right now. We would be squished to bits by the other planets.
