Answer:
AB = 21
Step-by-step explanation:
the line EB is parallel to the side of the triangle DC and intersects the other 2 sides proportionally , that is
= 
( substitute values )
= 
( cross- multiply )
12 AB = 14 × 18 = 252 ( divide both sides by 12 )
AB = 21
Answer:
C
Step-by-step explanation:
find the equation of the segment two point (-5,5) and (-2,-4)
m=y2-y1/x2-x1 =5-(-4)/-5-(-2) =9/-3 = -3
find b : y= -3x+b
5 =-3(-5) +b
b=-10
the equation is : y=-3x-10
the perpendicular line is y=1/3 x -2/3
Remember, -(-x)=x because the negatives cancel out
so
when p=-6 and q=7
p+(-q)-3
-6+(-7)-3
-6-7-3
-13-3
-16
It would be C because if you multiply each number of 6/2 by two you get 12/4. with B you divide by 3 to get 12/4. with D you divide by 20 to get 12/4. With C it isn't possible to get 12/4. So I would go with C
