Answer:
Step-by-step explanation:
Combine any like terms on each side of the equation: x-terms with x-terms and constants with constants. Arrange the terms in the same order, usually x-term before constants. If all of the terms in the two expressions are identical, then the two expressions are equivalent.
Answer:
Shortest distance from the mountain is 3.17 miles.
Step-by-step explanation:
From the figure attached,
Let a mountain is located at point A.
Angle between the mountain and point B (∠B) = 53°
Angle between the mountain and point C (∠C) = 78°
Distance between these points = 3 miles
Since, m∠A + m∠B + m∠C = 180°
m∠A + 53° + 78° = 180°
m∠A = 180°- 131° = 49°
By applying sine rule in triangle ABC,
AC =
AC = 3.17 miles
AB =
AB = 3.89 miles
Therefore, shortest distance from the mountain is 3.17 miles.
5 because you subtract 15x and bring it to 3x^2 and get 3x^2-15x=0. Then take out the gcf and you get 3x(x-5)=0. Since it can't be 0, x-5=0 , the answer is 5.
