Answer:
x>-2 and x<1
Step-by-step explanation:

Now dividing by 4:

So, x is the value between -2 and 1, i.e. x has to be greater than -2 and smaller than 1
Answer:
<h2>411,52 in²</h2>
Step-by-step explanation:
Surface area = 2×(6,8×8,2+6,8×10+8,2×10) = 411,52
Answer:
400 square meters
Step-by-step explanation:
We can first solve this problem with each unit representing 1 centimeter, and then scale up at the very end. The shape that we have a parallelogram. The base is 8 cm, and the height is 2 cm. The formula for the area of a parallelogram is just
, so the area of the parallelogram is 16 square centimeters. However, now we scale up. Since each centimeter correlates to 5 meters, each little box will correlate to 25 square meters. Therefore,
square meters is our answer
Answer:
Step-by-step explanation:
10+20+40=70
70*0.8=7*10*0.8=56 L (We Deliver)
total area =2*(10+20)*40+2*10*20=2*30*40+400=2400+400=2800 cm^2
2800*0.02=28*100*0.02=28*2=56 L (Go Parcels)
