Answer:
-5
Step-by-step explanation:
ab = dc
x+15= 3x+25
2x = -10
x = -5
substituting in ad and bc
-10+18 = 8
3-(-5)=3+5=8
A = 1/2 * b * h
A = 178.5
b = h + 4
178.5 = 1/2 * (h + 4) * h
357 = h^2 + 4h
h^2 + 4h - 357 = 0
(h - 17)(h + 21) = 0
h - 17 = 0
h = 17
h + 21 = 0
h = -21 .....not this one because it is negative
b = h + 4
b = 17 + 4
b = 21
so the height is 17 inches and the base is 21 inches <==
Answer:
350 feet per minute
Step-by-step explanation:
The amount of time it took the plane to descend is 3 hours 14 minutes minus 1 hour 30 minutes.
This means it took 104 minutes for the plane to descend 36,400 feet.
Dividing 36400 by 104, you get 350 which is the average rate of descent in feet per minute.
