Answer:

the given polynomial has two roots

Step-by-step explanation:

the polynomial function y=(x-8)(x+3)^2

To find the number of roots we look at the exponent of each factor

(x-8) has exponent 1 , x=8 is a root (one root)

(x+3)^2 has exponent 2 , x=-3 is one of the root

(x+3)^2=0

take square root on both sides

x+3=0

x= -3

So the given polynomial has two roots 8 and -3

Answer:

A. you need 2 1/2 ounces

B. you need 73,9 milliliters

Step-by-step explanation:

We have the ratio 1/2 ounces per gallon

And the mop bucket holds 5 gallons

Then we need to multiply 1/2*5

we got 2 1/2 ounces of desifectant per 5 gallons

1 ounces equal 29,57 milliliters

if we have 2 1/2 ounces then we multiply 2,5 *29,57

the answer is 73,9 milliliters

PLZZZZZZZZ HELP IM VERY STUCK ON THIS

Neporo4naja [7]

Answer:

B= 15 adults tickets

C= 35 student tickets

Step-by-step explanation:

x+y=50

solve for y

y=50-x

5x+3y=180

5x+3(50-x)=180

5x+150-3x=180

2x=30

x=15

y=50-15

y=35

VARVARA [1.3K]

Answer:

Solution :

{x,y} = {0/14261512,4}

Step-by-step explanation:

Solve by Substitution :

// Solve equation [2] for the variable y

[2] y = x + 4

// Plug this in for variable y in equation [1]

[1] 12x - 5•(x +4) = -20

[1] 7x = 0

// Solve equation [1] for the variable x

[1] 7x = 0

[1] x = 0

// By now we know this much :

x = 0

y = x+4

// Use the x value to solve for y

y = (-0/14261512)+4 = 4
