Answer:
Step-by-step explanation:
You have to work out the area of each side. The two identical triangles are 6x4=24 because 8/2 is 4. The base is 8x5=40. The back is 6x5=30 and the top is 10x5=50. You then add them all together to get 144 ft squared.
First multiply 180 and 25 which is 4500.
Then divide by 17 which should be approximately 264.71
Answer:
9(t+5)<6
t<-13/3
Step-by-step explanation:
