Answer:
3^3 * 7^r has (3 + 1)*(r + 1) = 16 factors.
So r must be 3.
Step-by-step explanation:
Total fat in mixture is 8x+15y100 pints.
Explanation:
In a mixture of x pints of 8% butterfat, we have 8x100 pints of butter
and in y pints of 15% butterfat, we have 15y100 of butterfat.
Hence total fat in mixture is 8x+15y100 pints.
put x=0 then y=4
put y=0 then x=-4
therefore 2 ccordintes are
(0,4) and (-4,0)
take a scale and construct a line joining these two points.
you will get the required graph.

Answer:
5x-2
Step-by-step explanation:
15x^2-x-2
15x^2+5x-6x-2
factorize
5x(3x+1)-2(3x+1)
Sol: (3x+1)*(5x-2)
