Why are you including the black royals???

CPhill answered this one!

Find the slope   [   5 - 11 ] / [ -4 - 1 ]  =  -6 / -5   =  6 / 5

Write the equation of the line in point-slope

y = ( 6 /5) ( x - 1) + 11

y = (6/5)x - 6/5  + 11

y = (6/5)x  - 6/5 + 55/5

y = (6/5)x + 49/5        multiply both sides by  5/49

(5 / 49)y =   (6 /49)x  + 1

- (6 / 49)x  + ( 5/49) y  =  1

And we can write  this as

x / ( - 49/6)  + y / (49 / 5)   =  1

a =  -49 /  6

This was literally posted yesterday.

Find BuilderBoi's answer. And, I think CPhill will give you one also!

OH MY GOD! DID YOU KNOW I DON'T READ JIBBERISH???!!!

Can you just upload the picture and not copy and paste the latex or whatever???

On my first try I got 16. But then I counted the triangles containing the smaller group!

why isn't it three

area of shaded region is called x.

Total area minus blank region= x

lets call area of blank region y

lets call total area z

\(z-y=x\)

\(z = (12\times9)/2\)

\(z=54\)

\(y=\frac{12\times5}{2}\)

\(y=30\)

Plug them in to get

\(54-30=x\)

\(x=24\)

Use Quadratic Formula to find roots \(a\) and \(b\) \( = - 3/2 +- \sqrt37 / 2\)

Use these values in\((2a-3)(4b-6)\)to find the answer .....

which is also BuilderBoi's answer!
