Answer: B and D are correct.
Step-by-step explanation:
A is wrong because they will eventually intersect (the arrows show that the line continues on).
B is correct; that is where they will intersect.
C is wrong because they only intersect at one point, and that's where the solution is.
D is correct because they intersect once and have only one solution.

Answer: x=57
///////////////////////////////////////////////////////////////////////////////////////////////////////
1/3(3x+9)=60
x+3=60
x=57
First, the factor pairs for 18 are:
1, 18
2, 9
3, 6
Since the middle term is -3, the two factors must be 3 apart. The only pair that is 3 values apart is 3, 6.
Since the middle value is negative, the larger number is negative. This means that the 6 is negative.
z = -6
z = 3
Set each equal to 0;
z = -6
z + 6 = 0
z = 3
z - 3 =0
So your factors are (z+6) and (z-3), or answer B.
Answer:
611 square miles
Step-by-step explanation:
Area of triangle = (1/2)*a*b*sinC (formula when u are not given the height of the triangle, but u are given with the angle.)
= (1/2)*30*47*sin(60°)
= 610.54 square miles (2 d.p)
≈611 square miles (rounded to nearest mile)
