I am fantastic!!
Step-by-step explanation:
I was painting today :D
A=1/2bh
b=8+h
A=384
384=1/2(bh)
times 2
768=bh
sub
768=b(8+b)
768=8b+b^2
minus 768 both sides
0=b^2+8b-768
factor
0=(b-24)(b+32)
set to zero
b-24=0
b=24
b+32=0
minus 32
b=-32
false, legnths cannot be negative
b=24
24=8+h
minus 8
16=h
base=24ft
altetude=16ft
487 + 310 ≈ 500 + 300 ≈ 800
45 times the numerator plus the denominator is most likely going to equal the same amount as if it were doubled.
