27ft. Would be the correct answer.
That box means 90degrees so you put them equal to each other 90 = 15X
90/15 = 6
So x = 6
Pi rounded to a whole number would equal three. Circumference equals 2pi*r. The radius in this case is half of the diameter, so 4.5 cm. 2 times pi, or three equals 6 times 4.5 is 27
Let the 4 integers be x, x+2 , x+4 , x+6 Then
4x + 12 = 7(x + 6)
4x + 12 = 7x + 42
3x = -30
x = -10
The integers are -10 -8 , -6, and -4 answer
