Answer:

Option D. (6x + 11)(x - 5)

Step-by-step explanation:

The given expression is 6x² - 19x - 55

We have to convert it into factored form as given in the various options.

6x² - 19x - 55 = 6x² - 30x + 11x - 55

6x(x - 5) + 11(x - 5)

(6x + 11)(x - 5)

Therefore, option D. (6x + 11)(x - 5) is the correct answer.

Jackie walks into a convenience store and recognizes the number of lottery tickets she can purchase varies inversely with the pr
OLEGan [10]
Let the price of the tickets be 'x' and the number of tickets bought is 'y'

When the y inversely proportioned to x, the equation is

y = k/x where k is a constant

We work out the value of k by using the information y = 6 and x = 5

6 = k/5
k = 30

Hence, the maximum number of tickets when the price is $3 is

y = 30/3
y = 10 tickets

Vinil7 [7]

Answer:

0.16 gallons of paint are used on each piece of furniture.

The answer lies between the whole numbers 0 and 1.

Step-by-step explanation:

we know that

Four gallons of paint are used to paint 20 chairs and 5 small tables.

if each chair and table used the same amount of paint

then

sum the total pieces of furniture

20+5=25 pieces

Find the unit rate

Divide the total gallons of paint used by the total pieces

\frac{4}{25}=0.16\ \frac{gallons}{piece}

therefore

0.16 gallons of paint are used on each piece of furniture.

The answer lies between the whole numbers 0 and 1.
