Sofia bought some flats of sies. each flat holds 9 daisies. sofia has planted10 daisies. is 9x 10 a reasonable way to represent the number of daisies thatsofia has left to plant? explain your answer.

Step-by-step explanation:

Let Sofia bought x flats of daisies.

Since each flat contains number of daisies = 9

Therefore, number of daises in x flats = 9x

If Sofia has planted 10 daisies then number of daisies left = 9x - 10

Therefore, expression shown (9x + 10) in the question is not valid to represent the number of daisies left with Sofia.

It should be (9x - 10).

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )
