If the first of three consecutive integers is subtracted from 138, the result is the sum of the second and third. What are the i
Murljashka [212]

Answer:

<h2>45, 46, 47</h2>

Step-by-step explanation:

n, n + 1, n + 2 - three consecutive integers

The equation:

138 - n = (n + 1) + (n + 2)

138 - n = n + 1 + n + 2                 <em>combile like terms</em>

138 - n = 2n + 3           <em>subtract 138 from both sides</em>

-n = 2n - 135               <em>subtract 2n from both sides</em>

-3n = -135            <em>divide both sides by (-3)</em>

n = 45

n + 1 = 46

n + 2 = 47

Solve for x. Round to the nearest tenth of a degree, if necessary.
ziro4ka [17]

Answer:

x ≈ 28.8°

Step-by-step explanation:

Using the sine ratio in the right triangle

sin x = \frac{opposite}{hypotenuse} = \frac{AB}{AC} = \frac{3.9}{8.1} , then

x = sin^{-1} (\frac{3.9}{8.1} ) ≈ 28.8° ( to the nearest tenth )

Elle is buying new flooring for her kitchen
const2013 [10]

Answer:

The total area of the two rooms is 188.25 square feet

Step-by-step explanation:

Given:

Area of the kitchen = 132 square feet.

Dimension of the Laundry room =  8 1/3 feet by 6 3/4 feet.

To Find:

The total area of the two rooms = ?

Solution:

Area of the two rooms   =  Area of the kitchen + Area of the laundry room

Area of the two rooms   =    132 +  Area of the laundry room

Area of the laundry room  =(8 \frac{1}{3}) \times (6 \frac{3}{4})

Area of the laundry room  =\frac{25}{3} \times \frac{27}{4}

Area of the laundry = \frac{675}{12}

Area of the two rooms   =    132 +  \frac{675}{12}

Area of the two rooms   = 132 + 56.25

Area of the two rooms   = 188.25 square feet

Use the Remainder Theorem to determine which binomial is a factor of the function f(x) = x3 − 2x2 − 19x + 20.
dybincka [34]

Answer:

(x - 1)

Step-by-step explanation:

Given

f(x) = x³ - 2x² - 19x + 20

The sum of the coefficients is 1 - 2 - 19 + 20 = 0

This means that x = 1 is a root and (x - 1) is a factor of f(x)
