Talja [164]

Answer:

$ 2250

Step-by-step explanation:

3375 = s³

s = ∛3375

s = 15 ft.

floor area = s² = (15 * 15)

floor area = 225 ft²

the contractor charges $10 per ft².

therefore,  

the hardwood cost = 225  x  $10 = $2250

X^2-4x+c find the value of c
Sonbull [250]

Answer:

c = 4

Step-by-step explanation:

Given

x^2 - 4x + c

Required

Find c

The question is incomplete. However, I'll assume the expression is a perfect square.

To find c, we make use of the following formula

c = (\frac{b}{2})^2

Where

ax^2 + bx + c

By comparison with x^2 - 4x + c

a =1

b = -4

So, c = (\frac{b}{2})^2 becomes

c = (\frac{-4}{2})^2

c = (-2)^2

c = 4

<em>The value of c that makes the expression, </em>x^2 - 4x + c<em> a perfect square is 4 and the expression is: </em>x^2 - 4x + 4<em></em>

X – 6y - 9 = 0 x = 8y + 6 What is a resulting equation?
serious [3.7K]

Answer:

-2y + 3 = 0

Step-by-step explanation:

x - 6y - 9 = 0

-6y - 9 = -x                          subtract x from both sides

6y + 9 = x                            divide both sides by -1

x = 8y + 6

6y + 9 = 8y + 6                    replace x with 6y + 9

-2y + 9 = 6                           subtract 8y from both sides

-2y + 3 = 0                            subtract 6 from both sides

Which pairs of quadrilaterals can be shown to be congruent using rigid motions?
Misha Larkins [42]

Answer:

1 and 2 are not congruent; 1 and 3 are congruent; 1 and 4 are congruent; 2 and 3 are not congruent; 2 and 4 are not congruent; 3 and 4 are congruent.

Step-by-step explanation:

From the diagram, we can see that the angle measures and side measures of figures 1, 3 and 4 are the same.  This means that these three figures are congruent.  Figure 2, however, is not congruent to any of the other 3.
