12 3/4 as a decimal is 12.75
The area of a rectangle is length times width.
So if you divide the area (12.75) by the length(3.4)
you will get a width (and answer) of 3.75 :)
Answer:
x = 0 or 
Step-by-step explanation:
We have the quadratic equation of variable x and we have to solve the equation using the square root property.
Now, we have x(3x - 17) = 0
⇒ 3x² - 17x = 0
⇒
⇒
⇒
Now,square rooting both sides we get,
Therefore, either x = 0 or

It would be B. 120 you would usually round up but the closest one to 129.02083 is 130 and since there is no 130 it would be 120
Answer:
13.636
Step-by-step explanation:
The area can be found using Heron's formula:
A = √(s(s-a)(s-b)(s-c))
where s=(a+b+c)/2.
For the given triangle, ...
a=9, b=4, c=12, s=(9+4+12)/2 = 12.5
A = √(12.5(3.5)(8.5)(0.5)) = √185.9375 ≈ 13.636
The area of the triangle is about 13.636 square units.
