Zeroes are when f(x)=0
0=x^2+9x+20
factor
0=(x+4)(x+5)
set each to zero
x+4=0
x=-4
x+5=0
x=-5
zeroes are f(-5) and f(-4)
If I could help I would but I don’t understand how to do it
The other angle would have to be 96 degrees, so the first option
Make a rectangular box that is 7/8 foot long, and 3/5 foot wide, then you just multiply the two together, I'm not gonna do it all for ya.
