Of multiplication or addition?
Answer:
3,9,27,81,243,729,2187
Step-by-step explanation:
each number up times it by 3
3x3=9 ,9×3=27, 27×3=81,81×3=243,243×3=729,729×3=2187 and so on
Answer:
x = 18 and y = 6√10
Step-by-step explanation:
First using pythagoras theorem on the small triangle
h² = 6² + 2²
h² = 36 + 4
h² = 40
h= √40
h = √4 * 10
h = 2√10
Using the similarity theorem;
y/2√10 = 6/2
y/√10 = 6
y = 6√10
To get x we will use the pythagoras theorem
y² = x²+6²
(6√10)² = x² + 36
360 = x² + 36
x² = 360 - 36
x² = 324
x = 18
Hence x = 18 and y = 6√10
