Answer:
x = 145°
Step-by-step explanation:
We know that y = 98°, so we can find ∠DBC:
180°-y = ∠DBC
180°-98° = 82°
We also know that z = 63°, therefore we can apply <u>exterior angle of triangles</u> to find x.
∠DBC + z = x
82°+63° = x
x = 145°
Answer:
c 1.33
Step-by-step explanation:
Answer:
Width = (3x^2) [m]
Length = (4x^2 + 2x + 5) [m]
Step-by-step explanation:
Area of the rectangle
Area = width * length
Area = 12x^4+6x^3+15x^2 [m^2]
The width of the rectangle (in meters) is equal to the greatest common monomial factor of the area.
If we factor the equation, we get
12x^4+6x^3+15x^2 = (3x^2)*(4x^2 + 2x + 5)
This means that,
Width = (3x^2) [m]
Length = (4x^2 + 2x + 5) [m]
Answer:
(2,4)
Step-by-step explanation:
the x values stays the same because you are reflecting over its axis. the 4 becomes positive
