I'm assuming this is how u wanted it to be solved if not give me more info on the problem and I'll redo it
Step-by-step explanation:
x= 3,y = 4
The equation factors as
.. (x +3)(x +4) = 0
By the zero-product rule, the roots are
.. x1 = -4
.. x2 = -3
You would use the Volume equation L*W*H=V
2 1/2* 3 1/2* 4 1/2= 39 3/8
47 students , <span>19 boys
so girls = 47 - 19 = 28
28/47 = 59.57%
answer
</span>59.57% <span>is the percentage of girls</span>
