Nonrigid transformation changes the size but not the shape.
Answer:
A. 10
Step-by-step explanation:
The perimeter is the sum of all the outside lengths
Therefore, to find the value of x, you must do:
x + x + 5 + x + 7 = 42
3x + 12 = 42
3x = 30
x =10
Answer:
x + 6 is not a factor of f ( x ) = x³ - 3x² + 2x - 8 because when -6 is substituted into the function, the answer is not 0.
Step-by-step explanation:
→ Substitute x = -6 into f ( x )
( 6 )³ - 3 × ( 6 )² + ( 2 × 6) - 8
→ Simplify
216 - 108 + 12 - 8
→ Simplify further

Step-by-step explanation: 2(4x+6)=
\,\,34-3x
34−3x
Since HJ is a midsegment, twice HJ is equal to EG.
8x+12=

−12
-12 to both sides.

Answer:

Step-by-step explanation:
The angle of shaded sector = 360-332 = 28°
The radius of sector, r = 15 ft
We need to find the area of the shaded sector. The formula for the area of the sector is given by :

So, the area of the shaded sector is equal to
.
