Since length*width=area, (x+12)*width=x²-144. Dividing (x+12) from both sides, we get (x²-144)/(x+12)=width. One formula we can use is that
(a²-b²)=(a-b)*(a+b). Since 144=12², that means that x²-144=(x-12)*(x+12). Plugging that in, we get (x-12)*(x+12)/(x+12)=(x-12)=width
Hello!
Let's write this as an equation.
3(x+3)=5x-3
First, let's simplify the parentheses.
3x+9=5x-3
Let's subtract 5x from both sides.
-2x+9=-3
We subtract 9 from both sides.
-2x=-12
We divide both sides by -2.
x=6
Therefore, the number is 6.
I hope this helps!
Answer:
i dont know but imma get the points for this
Step-by-step explanation:
just for your info 6 and 24
3 1/3 - 2/3 = 2 2/3
3 1/3+ 1 2/3 = 5
3 1/3 + 5 + 2 2/3 = 11
What language is that seriously
