Answer:
12
Step-by-step explanation:
A parallelogram has 4 sides. Opposite sides of a parallelogram are parallel and congruent.
Since one side has length p, its opposite side also has length p.
Since one side has length 17 ft, its opposite side also has length 17 ft.
The lengths of the 4 sides are p, p, 17 ft, and 17 ft.
The perimeter is the sum of the lengths of the sides, and it is 58 ft.
p + p + 17 + 17 = 58
2p + 34 = 58
2p = 24
p = 12
First you have to combine like terms which you would combine 8j and j which would be 7j+3=17 then subtract 3 from 17 giving you 14. And after that your left with 7j=14 then divide 7 on both sides giving you 2 as your answer.
Answer:d=-1
Step-by-step explanation: you subtract 8 from both sides to get -4d=4 then divide -4 to get d alone. Which will get you to -1=d
