2x-1+3x+15+9 so you are going to add 2x and 3x so that will be 5x+-1+9+15
-1+9=8+15=23 so that will be 5x/23 that will be 4.6
Answer:
51ft, 17ft, 39ft
Step-by-step explanation:
longest = x
2nd = x
3rd = x - 12
P = 107
a + b + c = Perimeter
x + x + x - 12 = 107
x -12 = 107
x = 119
x = 51
x = 17
x - 12 = 39

Step-by-step explanation:
Answer:
11 and 13
Step-by-step explanation:
the first (smaller) odd integer can be called x
the second (larger) odd integer can be called x+2
2(x+2)+x = 37
<em>[simplify . . .]</em>
2x+4+x = 37
3x+4 = 37
<em>[subtract 4 from each side]</em>
3x = 33
<em>[divide each side by 3; find smaller odd integer]</em>
x = 11
<em>[add 2 to find larger odd integer]</em>
x+2 = 13
