Solve the inequality. d/13 > -3
do not answer the question. just explain how to solve it because i do not understand.

x < -39

Step-by-step explanation:

d/13 is actually just 1/13d:

1/13d > -3

Then you multiply both sides by the reciprocal of 1/13 which is 13. You do this because you normally you would divide, but since you can't divide a fraction, you multiply by the reciprocal, which is just the flipped version.

13 × 1/13 > -3 × 13

It cancels out on one side, because you are multiplying by its opposite. Then you multiply 13 × -3. This is -39. But the thing is that, when you multiply or divide by a negative, you need to flip the inequality sign around.

x < -39

each side has a different length.  

step-by-step explanation:

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
