Answer:
Step-by-step explanation:
Perimeter of a rectangle = 2(l+b)
Let the length be x
then width = x-2
44 ft = 2(l+b)
44ft = 2(x + x-2)
44ft = 2(2x-2)
44 ft = 4x -4
44+4 = 4x
48 = 4x
x = 48/4 = 12
Length = <u>x = 12</u>
Width = <u>x-2 = 12-2 =10</u>
<u></u>
<u>Length is 12 and width is 10</u>
<u></u>
<u>check if its correct </u>
2(l+b) = 44
2(12+10)=44
2(22) = 44
Answer: The numbers are 14, 16 and 18.
Step-by-step explanation: First thing to note is that consecutive even numbers have a difference of 2 units between every two terms. That is, if the first number is a, the next would be a + 2, and the next would be a + 4, and so on.
Therefore the three consecutive even numbers shall be a, a + 2, and a + 4.
Our equation now becomes;
a + a + 2 + a + 4 = 48
3a + 6 = 48
Subtract 6 from both sides of the equation
3a = 42
Divide both sides of the equation by 3
a = 14
Therefore, the numbers are 14, 16 and 18.
Answer:
w = 3
Step-by-step explanation:
19w - 1 = 11w + 23
19w - 11w = 23 + 1
8w = 24
w = 3
