Step-by-step explanation:
Because the expression can be written as -10r2/2r2+4+5r/2r2+4+3/2r2+4
Answer: 8x+12
Step-by-step explanation:
perimeter equals (x+4) + (3x+2) + (x+4) + (3x+2) = x+4 + 3x+2 + x+4 + 3x+2 = 8x+12
20.015
Because there are 3 numbers before a thousand so 3 numbers behind the decimal are the thousandths.
Answer:
the sum of the digits of the smallest number 668 = 6+6+8 = 20
Step-by-step explanation:
3 consecutive even number: x, x+2, x+4
4x + 2*(x+4) = 3*(x+2) + 2006
6x + 8 = 3x + 6 + 2006 = 3x + 2012
6x - 3x = 2012 - 8 = 2004
3x = 2004
x = 668
the sum of the digits of the smallest number = 6+6+8 = 20
