<span>14 more than one-twelfth of some number, w:
14 + </span>
× w = 14 +
Perimeter is the sum of all three sides so in this case x+(3x+2)+(3x+2).
They also gave us the perimeter which is 39 so
39= x+(3x+2)+(3x+2)
Simplify so 39=7x+4. [x+3x+3x=7x and 2+2=4]
Then get x by itself so subtract 4 from both sides.
35=7x
Then divide both sides by 7 to get x by itself.
Which leaves us with
X=5
Answer:
i think you would multiply them but I'm not sure
Answer:
Infinitely many solutions.
Step-by-step explanation:
x+2y=-1
2x+4y=-2
-----------------
x=-1-2y
2(-1-2y)+4y=-2
-2-4y+4y=-2
-2+0=-2
-2=-2
infinitely many solutions
