Seventy tickets were sold for a concert at $510. Each adult ticket cost $9 and each children's ticket cost $5. Be x the entrance fee for adults and be y the entrance fee for children.

a) Write down the system of equations that represents the problem:

exactly you go it

step-by-step explanation:

answer: our required factorization will be

(3x+4)(x²-5)

step-by-step explanation:

since we have given that

now, we will write it as :

so, we get

5(3x+4)

similarly,

here, we get,

2(3x+4)

together it becomes,

hence, our required factorization will be

(3x+4)(x²-5)
