<span>15-h)*h=40
15h-h^2=40
h^2-15h+40=0
solve for h by quadratic formula:
a=1, b=-15, c=20
ans:
h=3.47 or 11.53 cm (height)
b=15-h=11.53 or 3.47 cm (base)</span>
Percent error = (estimate - real)/(real) * 100
percent error = (78.25 - 75.50)/(75.50) * 100
percent error = 3.6%
Answer:
b > 100
Step-by-step explanation:
Answer:

Step-by-step explanation:
The dimensions must be the same
10 yards = 10 × 3 feet = 30 feet
ratio =
= 
4(3+x)
This is because 4*3=12 and 4*x is 4x so you get 12+4x which is the original equation
