Vertex for is a(x - b)^2 + c
first divide 6x^2 + 12x by 6 so we have
6(x^2 + 2x) - 10
now complete the square on the expression in the brackets:-
= 6[ (x + 1)^2 - 1] -10
=6(x + 1)^2 - 6 -10
= 6( x+ 1)^2 - 16
Answer:
Step-by-step explanation:
6(k + 2) + 1 = 13 (distribute 6 around the k+2)
6k + 12 + 1 = 13 (add 12 and 1)
6k + 13 = 13 (subtract 13 from both sides)
6k = 0 (divide by 6)
k = 0
Divide 3 and 15 by three and get 1/3
Answer:
5/9 acres
Step-by-step explanation:
3 1/3 areas is 10/3
1/6 of the land is covered with beets

will simplify to 
Hence the answer is 5/9 acres
The external angle is equal to the sum of the other 2 interior angles
basically 109=6x+21+2x
109=8x+21
minus 21 both sides
88=8x
11=x
x=11 degreees
