Answer:
Given in a bag contains five green marbles, three blue marbles, two red marbles and two yellow marbles
(a)The four colour out comes not equally because the number of four colours balls are different.
(b) Total ball =5+3+2+1=11
Then probability (green) =
11

Then probability (blue) =

If a segment is horizontal, its length is the difference between its x coordinates. If the result is negative, you need to consider the absolute value (or just pick the coordinates in the correct order, i.e. the bigger minus the smaller).
So, we have


The axis of symmetry is -2
Answer:
16.64645cm²
Step-by-step explanation:
All of the angles are equal: A = B = C = 180/3 = 60°.
All of the sides are equal: a = b = c.
h = 5 cm, sin60 = h/a = 5/a, a = 5/sin60 = 5.77 cm.
Area = 1/2bh = 1/2 x 5.77 x 5.77 = 33.2929/2 = 16.64645cm²
Answer:
B
Step-by-step explanation:
Given
2(5x + 8) = 6x + 20 ← distribute parenthesis on left side
10x + 16 = 6x + 20 ( subtract 6x from both sides )
4x + 16 = 20 ( subtract 16 from both sides )
4x = 4 ( divide both sides by 4 )
x = 1 → B
