Looking for the height, if trapezoid area equals (a+b)/2 x h then h = 2A/(a+b)
so h = 2(30)/(4.8+5.2) = 6
Answer :
x = - 12 for y = - 4
Step-by-step explanation:
Given as y = - 6 when x = - 14
write in equation form
I.e y = x + c
Put x and y values ,
So, c = y - x
c = - 6 + 14 = 8
Now when y = - 4 and c = 8 ,
So, from eq x = y - c
∴ x = - 4 - 8 = - 12 Answer
