Answer:
Step-by-step explanation: The correct answer(s) are B.-2.76, C. -2 1/4, and D. -11/4
Answer:
(- 2, - 3 )
Step-by-step explanation:
Given the 2 equations
2x - 4y = 8 → (1)
y = x → (2)
Substitute y = x into (1)
2x - 4( x ) = 8
2x - 6x = 8
- 4x = 8 ( divide both sides by - 4 )
x = - 2
Substitute x = - 2 into (2) for corresponding value of y
y = × - 2 = - 3
Solution is (- 2, - 3 )
It has six sides and six angles.
Lengths of all the sides and the measurement of all the angles are equal.
The total number of diagonals in a regular hexagon is 9.
The sum of all interior angles is equal to 720 degrees, where each interior angle measures 120 degrees.
Answer:
D) 9×3
Step-by-step explanation:
Because -
3×3=9
9×3= 27
Or else-
3×3×3=27
