Answer:
3n^2 (9+25n)
Step-by-step explanation:
We need to perform multiplication and addition property for this problem to represent the final result in decimal form. So, the expression is,
9x100+2x10+3x0.1+7x0.001 .
Now 9 x 100= 900
2 x= 10= 20
3x0.1= 0.3
7x 0.001=0.007
Now we can all the numbers. Hence,
900+20+0.3+0.007=920.307
So, the decimal number is 930.307.
X^2+2x-5x-10
x(x+2)-5(x+2)
(x-5)(x+2)
