Answer:

{x}^{2}  + 3x  - 10

Step-by-step explanation:

(x + 5)(x - 2)

utilise the Foil method to expand brackets:

F - mulply the first terms (x and x)

O - multiply the outside terms ( x and -2)

I - multiply the inside terms (5 and x)

L - multiply the last terms (5 and -2)

Then add them as following:

{x}^{2}   - 2x + 5x - 10

Then combine like terms:

{x}^{2}  + 3x - 10

Tell the maximum number of zeros that the polynomial function may have. then use​ descartes' rule of signs to determine how many
Marta_Voda [28]
F(x) = -4x^7 +x^3 -x^2 +5

a) It is a degree 7 polynomial, so will have 7 zeros (some may be repeated).

b) has 3 sign changes, so 1 or 3 positive real zeros. If odd powers have their signs reversed, the signs are changed to +--+, so there are 2 sign changes. There will be 0 or 2 negative real zeros.

____
There is actually 1 positive real zero and 0 negative real zeros. This means there are 3 conjugate pairs of complex zeros.

An animal shelter houses ferrets, cats, and dogs. There are 108 animals at the shelter. Of the
Korvikt [17]

Number of dogs in the shelter are 12

<u>Step-by-step explanation:</u>

Step 1:

Given that total animals = 108 and number of ferrets = 1/3 of 108. Find number of ferrets in the shelter.

Number of ferrets = 1/3 of 108 = 1/3 × 108 = 36

Step 2:

Given that of the remaining animals, number of cats = 5/6. Find the remaining animals and the number of cats.

Remaining number of animals = 108 - 36 = 72

Number of cats = 5/6 of 72 = 5/6 × 72 = 60

Step 3:

Find number of dogs in the shelter.

Number of dogs = 108 - (36 + 60) = 108 - 96 = 12
