-3x^2+10x-3
This is of the form ax^2+bx+c. We need to find two values, j and k, such that:
jk=ac=9 and j+k=b=10, so j and k must be 1 and 9.
Now replace bx with jx and kx in the original equation...
-3x^2+x+9x-3 now factor 1st and 2nd pair of terms
-x(3x-1)+3(3x-1)
(-x+3)(3x-1) or equivalently...
-(x-3)(3x-1) or as they put it:
-(3x-1)(x-3)
The first loan charges more with $600 . The second loan charges $580.
Answer:
16/9
Step-by-step explanation:
We can find the slope given two points by using the following formula
m = (y2-y1)/(x2-x1)
= (0--16)/(3-12)
= (0+16)/(3-12)
=16/9
11.8 x 5.8= 68.44
now to find the length of the other side of the triangle,
11 - 5.8= 6
6 x 7.5= 45 ÷ 2= 22.5
22.5 + 68.44= 90.94
