Find two positive consecutive odd integers whose products is 99.
tensa zangetsu [6.8K]

Answer:

9,11

Step-by-step explanation:

let the numbers be x, x+2 (since consecutive odd integers have a difference of 2)

therefore;

x(x+2)= 99

x²+2x=99

I usually solve the sum like this,

we need to find the nearest square number ( number smaller than the number on the R.H.S)

here, it is 81, whose square root is 9. therefore the solution is 9

verification:

(9)²+2*9=99

81+18=99

99=99

hence, 9 is the solution. therefore the positive odd consecutive integers are  

x=9

x+2=9+2= 11

verification:

9*11=99

99=99

L.H.S=R.H.S

If f(x)=8-10x and g(x)=5x+4 what is the value of (fg)(-2)?
Shalnov [3]
First, calculate f(g(x))==> you plug (5x+4) in the value of x in f(x)

==>f(g(x))= 8-[10(5x+4)===>8-50x-40===>f(g(x))= -50x  + 32

& f(g(-2))= -100+32 =68.

There is a mistake in your answers, it should be 68 & not 78
