Look at!!:
Pre image A(3,4), B(1,5) C(6,6);
If you multiply these coordinates by 3/2, you get its images:
A(3,4) ⇒ A`(3*3/2, 4*3/2)=(4.5, 6)
B(1,5) ⇒B`(1.*3/2, 5*3/2)=(1.5, 7.5)
C(6,6) ⇒C`(6*3/2, 6*3/2)=(9,9)
Therefore the scale factor is 3/2.
When the scale factor of a dilation is >1, then we have an enlargement, an expansion.
In this case 3/2=1.5>1
Answer:
The dilation is expansion.
The scale factor is 3/2.
Answer:
I am a 4th grader I don't know
Step-by-step explanation:
Answer:
65 square units
Step-by-step explanation:
The base of the pyramid is 5 by 5 , surface area is 25 square units.
the side of each one is 4 units "high" and 5 long at the base and to find the are of a triangle you multiple base times height then dived by 2. Therefore each side of the triangle is 10 units square. You have 4 sides so...
40 (total of all the sides ) +25 ( base ) = 65
COB and COD complementary
AOB and BOC adjacent angle that is neither comp. or supp.
AOC and COD supplementary
AOE and COD vertical
Answer:
3x + 2
Step-by-step explanation:
6x + 1 - (3x-1) < distribute the negative sign into the expression
6x + 1 -3x + 1 < combine like terms
6x - 3x = 3x
1 + 1 = 2
our simplified expression is:
3x + 2
