Answer: 180 ft²

Step-by-step explanation:

The rest of the question is:

The living room is 18 feet wide and 10 feet long.

The floor seems to take the shape of a rectangle because it has one dimension being longer than the other.

As this is a rectangle, the floor area will be calculated by the formula:

= Length * Width

= 10 * 18

= 180 ft²

Answer:

Set the denominator in 4x equal to 0 to find where the expression is undefined. x=0

The domain is all values of x that make the expression defined.

Interval Notation: (−∞,0)∪(0,∞)

Set-Builder Notation: {x|x≠0}

The range is the set of all valid y values. Use the graph to find the range.

Interval Notation: (−∞,4)∪(4,∞)

Set-Builder Notation: {y|y≠4}

Determine the domain and range.

Domain: (−∞,0)∪(0,∞), {x|x≠0}

Range: (−∞,4)∪(4,∞), {y|y≠4}

Answer:

62

Step-by-step explanation:

5 * 3 * 2 = 30

3 * 2 * 2 = 12

5 * 2 * 2 = 20

30 + 12 + 20 = 62

Answer:

Step-by-step explanation:

One

v^2 - 16

This formation is called the difference of squares. That's because there are 2 squares v^2 and 16. The key to this question is the minus sign.

The square root of v^2 = v

The square root of 16 = 4

You get (v + 4)(v - 4)

Let's see what happens when you expand it.

Look what happens when you add these 4 terms together.

is what is left. The two middle terms cancel out.

Two

This one is a perfect square

w^2 + 16w + 64

(w + 8)(w + 8)

Notice both factors are the same. You might wonder how I new that.

w^2 is a perfect square so take the square root.  ....   v      

64 is a perfect square so take the square root    .....    8

Now you have to work backwards to see if it is right.

Adding you get w^2 + 16w + 64 which is what you started with.

Step-by-step explanation:

Answer:

[tex]y = \frac{7}{6} x[/tex]

Step-by-step explanation:

Slope-intercept form is

[tex]y = mx + b[/tex]

Where m = slope,

and b = y-intercept.

The problem states that the slope is [tex]\frac{7}{6}[/tex], and it also states that one point on the line is the origin. (0, 0)

Because the origin crosses the y-axis at point 0, we know that the y-intercept is 0.

All that's left to do is plug these values into the slope formula.

[tex]y = \frac{7}{6} x + 0[/tex]

We can then simplify the equation even more.

[tex]y = \frac{7}{6} x[/tex]

Step-by-step explanation:

Answer:

326

Step-by-step explanation:

First you find the area of the triangles. Since squares have equal sides we know that the triangle has a side of 20 and 12. We plug this information into the formula A=20x12/2 which equal 120 but since we have 2 triangles we multiply by 2 and get 240. Then we find the area of the square which is 400 when you multiply 20x20. Then you find the area of the circle which is 3.14x10^2 which equals 314. You add 240 and 400 to get 640. You subtract 460 from 314 and get 326.

Answer:

2

Step-by-step explanation:

so (+35) can be written as 35 because it's automatically already positive. +(-33) can be written as -33 because of one negative sign and one positive sign (if it was two negative or two positive, it would be positive). it's the same as 35-33, and 35-33=2.

Answer:

(+35) + (-33)

⇒ 35-33

⇒2

Answer:

4y

Step-by-step explanation:

Hey There!

given the equation

y - (-3y)

the two negative signs cancel out and make it into

y + 3y which is equal to 4y

thus meaning the answer to your problem is 4y

Answer:

first you need to set up the equation which is 20+2x=44 then isolate 2x by doing the inverse operation for 20 which is -20 and add them to both sides which would now give you 2x=24 so divde 24 by 2 which is 12, x=12 answer 12ml

Answer: $10,747.83

Step-by-step explanation:

The first interest payment is based on the full amount of the loan because no principal has been paid off yet.

Loan is:

= 209,000 * ( 1 - 15%)

= $177,650

Interest = 177,650 * 6.05%

= $10,747.83

Answer:

he should let the other angle be x

then according to question

Answer:

  A"(-6, 3)

  B"(-9, 0)

  C"(-5, -1)

Step-by-step explanation:

We presume the first transformation is a translation 4 units right and 1 unit up:

  (x, y) ⇒ (x+4, y+1)

The second transformation negates the x-coordinate, so the two transformations together have the rule ...

  (x, y) ⇒ (-(x+4), y+1)

Then the transformed points are ...

 A"(-6, 3)

  B"(-9, 0)

  C"(-5, -1)

Answer:

(n + 1) (2n - 7)

Step-by-step explanation:

2n^2 - 5n - 7

AC= 2 * -7 = -14

                -7 + 2 = -5

      2n^2 - 7n      + 2n - 7

     1n(2n - 7)       1(2n - 7)

(n + 1) (2n - 7)

Answer:

-8n

Step-by-step explanation:

2n²-5n=-1n

-1n-7=-8n

Answer:

∠ BAD = 25°

Step-by-step explanation:

AC and BC are both radius of the circle and are congruent, then

Δ ABC is isosceles with base angles A and B congruent , so

∠ BAD = [tex]\frac{180-130}{2}[/tex] = [tex]\frac{50}{2}[/tex] = 25°

Answer:

21/50, 42%

Step-by-step explanation:
