Answer:
Step-by-step explanation:
let the integers be x and y
x+y=-20
y=-20-x
xy=99
x(-20-x)=99
-20x-x²=99
x²+20x+99=0
x²+11x+9x+99=0
x(x+11)+9(x+11)=0
(x+11)(x+9)=0
x=-11,-9
when x=-11
-11+y=-20
y=-20=11=-9
when x=-9
-9+y=-20
y=-20+9=-11
so integers are -11,-9
Answer:
123 full pages
Step-by-step explanation:
Given


Required
Determine the number of full page
To do this, we simply divide the total stamps by stamps in each page;



Then we record only the quotient
The quotient is the digits before the decimal

<em>Hence, she has 123 full pages</em>
Answer:
Dividing exponents you subtract.
3^8/3^5 = 3^3
3^3
