Answer:
150 laptops because 70% of the total devices are laptop computers and desktop computers so the remaining 30% of the devices are tablet. 500×0.30= 150.
Let L = Length, and W = Width. We are given the fact that L = 2W, and also know that the area = L x W = 50 square feet. So, by substitution: 2W x W = 50 sq ft, or 2W^2 = 50 sq ft, so W = sq rt (50/2) = 5 ft. Now, L = 2W = 2(5) = 10 ft. The perimeter of the fence is given by: 2L + 2W = 2(10 ft) + 2(5 ft) =20 ft + 10 ft = 30 ft. So, Ben needs 30 ft of fencing.
Well you can automatically eliminate, A, because when you multiply one number that's positive and another number that's negative the result is always going to be negative.
However, when you multiply two negatives the result is always positive!
So, the only ones up there that would result in a positive number is B and C
***D. was not posted so I cannot determine that one!
