Answer:
{-12,0}
Step-by-step explanation:
first to solve this can collect like terms and add
X² +12x=0
and solve it by factorization method
X² +12x=0
x(x+12)=0
it means x multiplied by x = X² then x multiplied by 12 = 12x
so this means x or (x+12) equals to zero
x=0 and (x+12)=0
x+12=0
x=-12
so the solution set is {-12,0}
but can also be done by formula method
Answer:4
Step-by-step explanation:
H= 2*26/5+8
Answer:
2%
Step-by-step explanation:
the amount reserved in % is ($90÷$4500)×100=2%
so the $90 since is the amount you need to divide by the actual profits
and multiply by 100 for you to get the amount in %
Answer: The two equations that represent the conditions in the problems are 

Step-by-step explanation:
Since we have given that
Cost of 3 sparrows = $1
Cost of 2 turtle doves = $1
Cost of 1 dove = $2
Number of birds = 30
total cost = $30
So, Cost of s sparrows would be

Cost of t turtle doves would be
Cost of d doves would be

According to question, it becomes,

and

Hence, the two equations that represent the conditions in the problems are
