if your just factoring out then this should help x2 + 12x + y2 - 18y if they want something else i'm sorry
Answer:
110000
Step-by-step explanation:
If you have a number x then the consecutive number is x+1
the multiplication of two consecutive numbers can then be written as x*(x+1)=...
if you find an integer solution for this equation you can write the number as two consecutive integers multiplied with each other, if not you found the exception you are looking for
E)
x(x+1)=9900
x²+x=9900
-> complete square
x²+x+(1/2)²=9900+(1/2)²
(x+(1/2))²=9900+(1/4)
x+(1/2)=sqrt(9900+(1/4))
x=sqrt(9900+(1/4))-(1/2)
x=99
->9900=99*(99+1)=99*100
if we replace 9900 in the last lines with the other numbers we can check them quickly too:
F)
x=sqrt(15750+(1/4))-(1/2)
x=125
->15750=125*(125+1)=125*126
G)
x=sqrt(20448+(1/4))-(1/2)
x=142.497...
->not an integer
->can not be written as two consecutive numbers multiplied
H)
x=sqrt(38612+(1/4))-(1/2)
x=196
->38612=196*(196+1)=196*197
so G is the only number which can not be written as two consecutive integers
Answer:
120 is the answer, if we multiply 35×12= 420 apartments and there is 300 with 2 bedrooms. 420-300= 120 apartments with 1 bedroom. I hope it was helpful!
Answer:
The value of r is 4
Step-by-step explanation:
In order to find the value of r, you need to get rid of denorminator. By multiplying 4 to both sides:
(r/4)×4 = (60/120)×4
r = (1/2)×4
= 2
