I took the test and it’s Z
Yea it is one rational experisson
X1=4x5 I think it is. Though this would then give x=20x with I think is impossible...
Area=1/2 times base times height
area=60
height=12
60=1/2 times base times 12
divide both sides by 12
5=1/2 times base
multipy both side sby 2
10=base
10 units=base
