47.60 + 0.20(47.60) = 47.60 + 9.52 = 57.12
OR
47.60(1.20) = 57.12

Answer:
85/2 or 42.5 ft²
Step-by-step explanation:
A = l x w
A = 7.5 (5 2/3)
= 15/2 (17/3)
= 255/6
= 85/2 ft² or 42.5 ft²
Divide each term by 3...
15n - 8 = 3(5n - 6)
Let's find the discriminant of <span>x^2+9x+14=0. Here, a=1, b=9 and c=14.
The discriminant is b^2-4ac. Substituting the above numeric values,
9^2-4(1)(14) = 81-56 = 25
The sqrt of 25 is 5. Thus, your polynomial has two unequal, real roots.
Off the point example: If the discriminant were zero, your poly would have two real, equal roots.</span>
