10 because 30 divided by 10 equals 3 and 50 divided by 10 equals 5 and 3 and 5 only have a GCF of 1 so 10 is your answer
All the sides add like a rectangle with two sides measuring 4 and two measuring 2 so you would add 4+4+2+2=12
Answer:
AC = 24
Step-by-step explanation:
DE is the midline of the triangle, parallel to AC. It is half the length of AC, so ...
2·DE = AC
2(2x -14) = 3x -15
4x -28 = 3x -15 . . . . . eliminate parentheses
x = 13 . . . . . . . . . . . . . add 28-3x to both sides
AC = 3x -15 = 3(13) -15
AC = 24
_____
<em>Additional comment</em>
DE = 2(13) -14 = 12, half the length of AC.
Answer:
x-29/2
Step-by-step explanation:
Answer:
504/(surface area of all walls)
Step-by-step explanation:
Assuming Length=l, breadth=b and height=h
Surface Area of all walls= 2×l×h+2×b×h
Cost per square ft of wall paper= 504/(surface area of all walls)
