Answer:
8:05 am is the time she will have to leave her house to get to the airport on time.
Step-by-step explanation:
First, subtract 55 minutes from 10:20.
10:20 - 20 = 10:00
10:00 - 35 = 9:25
This is the time she wants to arrive. 9:25
Now, we have to subtract an hour and 20 minutes
9:25 - 1:00 = 8:25
8:25 - 20 = 8:05
Hope this helped and have a great day! :)
Answer:
A Tessellation (or Tiling) is when we cover a surface with a pattern of flat shapes so that there are no overlaps or gaps.
Step-by-step explanation:
A Tessellation (or Tiling) is when we cover a surface with a pattern of flat shapes so that there are no overlaps or gaps.
Secondly, to make a tessellation through equations, you mostly look at the number of vertex's in a tessellation.
If you identify patterns, you can easily tell what kind of tessellation it is.
For example, a 6.6.6 tessellation is a tessellation where three hexagons meet at the same vertex, and each hexagon has 6 sides.
To name a tessellation, go around a vertex and write down how many sides each polygon has, in order ... like "3.12.12".
Answer:
Step-by-step explanation:
2x²-2x-12 = 2 (x²-x - 6)
but : x²-x - 6 = x² - 2(1/2)x +(1/2)² - (1/2)² - 6
= ( x - 1/2)² - 1/4 - 6
= ( x - 1/2)² - 25/4
x²-x - 6 = ( x - 1/2)² - (5/2)²
by identity ; a² - b² = (a - b ) ( a +b)
x²-x - 6 = ( x - 1/2 - 5/2) ( x - 1/2 +5/2)
x²-x - 6 = (x - 3) (x +2)
so : 2x²-2x-12 =2(x - 3) (x +2) = (2x-6)(x+2) .......(factored form)
now : 2x²-2x-12 = 0 : 2x - 6 = 0 or x+2 = 0
x= 3 or x = - 2 two solutions
