Answer:
351
Step-by-step explanation:
The top box draw a line and then it will be just 9*9
then you have 30ft * 9ft
30*9 = 270
9*9 = 81
270+81 = 351
X = 6
CMON MAN THIS IS 5th GRADE MATH!!
Lets find all the numbers..
x (1st number)
x + 2 ( 2nd number)
x + 4 (3rd number)
x + 6 (4th number)
x + 8 (5th number)
x + 10 (6th number)
Now add all those expressions and set them equal to 270 because that is the total.
x + x + 2 + x + 4 + x + 6 + x + 8 + x + 10 = 270
6x + 30 = 270
6x = 240
x = 40
Now we will substitute 40 for x in the expression of the second number.
x + 2
40 + 2
42
So the second number is 42
Hope this helps :)
