What is nine plus six divided by (8-2) \

svet-max [94.6K]

Hey there mate ;),

According to given conditions, your question is :

$\frac{9 + 6}{8 - 2}$

So, now calculating,

$\frac{15}{6}$

Now lets solve by reducing to lowest terms,

$→ \frac{15}{6} = \frac{5}{2}$

Now by dividing, we get,

$→2.5$

Therefore, 

$\frac{9 + 6}{8 - 2} = 2.5$

the length of a rectangular floor is 5 feet less than twice its width the area of the floor is 150 square feet what is width of

asambeis [7]

Think of it like an equation: (w = width, l = length)

5 = 2w - l
lw = 150

l = 150 / w
5 = 2w - (150/w)
5w = 2w^2 - 150
2w^2 - 5w - 150 = 0 <- you can see this is now a quadratic equation

w = (-b^2 + sqrt(b^2 - 4ac))/2a
w = 10

width = 10
