Answer:
x=3, y=4. (3, 4).
Step-by-step explanation:
x+y=7
x+2y=11
--------------
-x-y=-7
x+2y=11
--------------
y=4
x+4=7
x=7-4
x=3
we are given trapezoid
Area is 104cm^2
a=4x-1 cm
b=x+2 cm
h=8cm
we can use area formula
we can plug above values
now, we can solve for x
so, we get
length of longer base is a
we can plug x=5 into a

460. 100%
74. X
X= 100•74/460
X=16.09%
2.)
175 100%
172. X
X=172•100/175
X=98.28%
