Answer:
0
Step-by-step explanation:
To solve this equation, first find out 4y, which equals 16. Then do the full equation, 16-16=0.
First you have to isolate the y value
to start, subtract 2x on both sides
3y=-2x+9
next, divide by 3
y= -2/3x+3
It is a <span>Concave pentagon because it has an angle over 180 degrees. Otherwise it is a Convex pentagon.</span>
Answer:
The only option 3 is correct
Step-by-step explanation:
See the given diagram.
1. ∠ D = ∠ B {Since AB ║ DE and DB is transverse line. So, they are alternate angles.}
So, ∠ D = 43° ≠ 28°
2. Now, ∠ A = ∠ CED {Again they are alternate angles}
⇒ ∠ A = ∠ CED = 180° - ∠ CEF = 180° - 152° = 28° ≠ 43°.
3. Again, ∠ ACD = 180° - ∠ ACB = ∠ A + ∠ B = 28° + 43° = 71°.
4. ∠ BCE = ∠ ACD {Vertically opposite angles}
⇒ ∠ BCE = 71° ≠ 109°
Therefore, the only option 3 is correct. (Answer)
Answer:
2√3
Step-by-step explanation:
root 27
= √27
= 3√3
12 upon root 3
= 12 / √3
= ( 12 / √3 ) x ( √3 / √3 )
= ( 12 x √3 ) / ( √3 x √3 )
= 12√3 / 3
= 4√3
6 upon √3
= 6 / √3
= ( 6 / √3 ) x ( √3 / √3 )
= ( 6 x √3 ) / ( √3 x √3 )
= 6√3 / 3
= 2√3
root 3 = √3
root 3 + root 27 - 12 upon root 3 + 6 upon root 3
= √3 + 3√3 - 4√3 + 2√3
= 4√3 - 4√3 + 2√3
= 2√3
