We have a trapezoid and a triangle
area of trapezoid=(base1+base2) times 1/2height
area of traingle=1/2 base times height
triangle
base=18
height=12
area=1/2 times 12 times 18=108
trapezoid
to find height we do
17=12+height
subtrac 12
5=height
so
base1=14
base2=18
height=5
area=(14+18) times 1/2 times 5
area=32 times 1/2 times 5
area=80
total area=area of trapezoid+area of triangle
total area=80+108
total area=188 mm^2
(9m)^4 means 9m is multiplied by itself 4 times:
It can be written as: (9m)(9m)(9m)(9m)

The formula for this is
. Filling in accordingly,
. This simplifies to
and 36=6x. Therefore, x = 6 so the bases are 6 and 12.
Answer:
either 76 or 19
Step-by-step explanation:
76 if it's 1/5 of the original amount as well as 3/4 the original amount
1/5+3/4=19/20
3.80=1/20x
3.80+19/20x=76
3.8*20=76
19 if it's 1/5 of the original amount and 3/4 of the new amount
3.80=1/4y
3.80+3/4y=15.20
15.20=4/5x
15.20+1/5x=19
