Answer:
Step-by-step explanation:
Add 6 to both sides:
Subtract 9m from both sides:
Divide both sides by -3:
Answer:
3
Step-by-step explanation:
Simplify: (-7x2 - 3x) - (4x2 - x) ... -11x2 – 2x ... 3x – 5 + 23x – 9 = 3x + 23x – 5 – 9 = 26x – 14 = 2(13x – 7) Answer: 2(13x – 7). 11 . ... 2x - 3 + 3 = - 9 + 3, (Adding 3 on both sides) 2x = -6 2x/2 = -6/2
Answer:
amplitude = 3
Step-by-step explanation:
the amplitude is the vertical distance from center of the wave to the crest or the trough
Step-by-step explanation:
Left hand side:
tan 203° + tan 22° + tan 203° · tan 22°
From angle sum identities, we know:
tan (α + β) = (tan α + tan β) / (1 − tan α · tan β)
Therefore:
tan (203° + 22°) = (tan 203° + tan 22°) / (1 − tan 203° · tan 22°)
tan (225°) = (tan 203° + tan 22°) / (1 − tan 203° · tan 22°)
1 = (tan 203° + tan 22°) / (1 − tan 203° · tan 22°)
tan 203° + tan 22° = 1 − tan 203° · tan 22°
Substituting:
1 − tan 203° · tan 22° + tan 203° · tan 22°

Answer: 
Step-by-step explanation:
The given regular polygon has 3 sides, therefore, it is a triangle with all sides equal and called equilateral triangle.
The area of equilateral triangle is given by:-
, where a is the side length of equilateral triangle.
Now, the area of given equilateral triangle with sides = 16 ft. is given by:-
