<span>Julia is X+5
</span><span>x+x+5=31
</span>
Now we just solve the equation
2x=31-5
x=26/2
x=13 years old (Babs' age)
and we know that julia is 5 years older this gives us the conclusion that.
13+18=31
1. A (x²-4y)³
2. ?=5
3. (x+3)(3y-5)
4. (4y+7)(5x-1)
With the given order of integration, the interval over D is
