Answer:
Shortest Side = 20 feet
Second Side = 23 feets
Third Side = 37 feets
Step-by-step explanation:
Let the shortest side of the desk be x. Hence,
Second side = (x + 3) feets
Third side = (2x - 3) feets
Perimeter = 80ft
x + (x + 3) + (2x - 3) = 80
4x = 80
x = 20
Hence, Second side = (20 + 3) feets
= 23 feets
Third side = (40 - 3) feets
= 37 feets
Hence<u>,</u><u> shortest side is 20 feets, Second side is 23 feets, Third side is 37 feets.</u>
Hey there!
Here's your answer: m<2=114.52 degrees
Here's how I got it: we know that a linear pair of angles is supplementary, aka the sum of the angles is 180 degrees.
you would add 18x-1 and 23x+7 together to equal 180 and solve for x.
then, you would substitute x for 4.24 (rounded) into 23x+17
23(4.24)+17=114.52
Hope this helps!
This can't be factored with rational numbers.

Answer:
750 units.
Step-by-step explanation:
30 x 30 = 900 units (total space in the classroom)
2 x 3 = 6 units (how much space each desk takes up)
25 x 6 = 150 units (number of desks for each student)
900 - 150 = <u>750 units</u>
Hope this helped!
