Answer:

One of the factor is (2h+1)

Step-by-step explanation:

-2h^2-15h-7

Take out negative sign in common

-(2h^2+15h+7)

Now factor the parenthesis

To factor this , we find out two factors whose product is 14 and sum is 15

-(2h^2+h+14h+7)

Break first two terms and last two terms

-(2h^2+h)+(14h+7)

-h(2h+1)+7(2h+1)

(-h+7)(2h+1)

(7-h)(2h+1)

One of the factor is (2h+1)

Ksju [112]

A total of 1,716 selections of the 7 flowers are possible.

Step-by-step explanation:

Step 1:

There are 13 flowers from which Jeanine Baker plans to use 7 of them.

To determine the number of selections that are possible we use combinations.

The formula for combinations is; ^{n} C_{r}=\frac{n !}{(n-r) ! r !}.

Step 2:

In the given formula, n is the total number of options and r is the number of options to be selected.

For this question, n = 13 and r=7.

So ^{13} C_{7}=\frac{13 !}{(13-7) ! 7 !} = \frac{13 !}{(6) ! 7 !} = 1,716.

So a total of 1,716 selections are possible.
