Answer:

469.9 ft^2

Step-by-step explanation:

The rate at which soil covers the garden is:

  125.3 ft^2  /  (1 bag)

If Stephanie has 3 3/4 bags of soil to start with, the area she can cover with this soil is (rate)(number):

   125.3 ft^2          15 bags

Option D is correct

2x^3 - 7x^2 + 4x - 3

Step-by-step explanation:

= x(2x^2 - x + 1) -3 (2x^2 - x + 1)

= 2x^3 - x^2 + x - 6x^2 + 3x - 3

= 2x^3 - x^2 - 6x^2 + x + 3x - 3

= 2x^3 -7x^2 + 4x -3 (Ans)

Answer:

x = 17

Step-by-step explanation:

number of sides (n) = 5

Sum of angles of polygon = (n - 2) *180

                                            = 3 * 180 = 540

9x + 71 + 92 + 5x + 139 = 540

9x +5x + 71 + 92 + 139 = 540

                   14x + 302   = 540

                               14x  = 540 - 302

                                14x = 238

                                    x = 238/14

x = 17

Answer:

8x + 11y + 6

Step-by-step explanation:

5x + 2x + x = 8x

3y + 8y = 11y

6

8x + 11y + 6

Answer:

y = -2/3x + 5

Step-by-step explanation:

Find the slope by doing change in y / change in x:

-1 / 1.5 = -2/3

Then, put the equation in point slope form:

y - 5 = -2/3(x - 0)

y - 5 = -2/3x

y = -2/3x + 5

Answer:

16a - 6b + 6

Step-by-step explanation:

5a + 5b - 5 + 11a - 11b + 11 = 5a + 11a + 5b - 11b - 5 + 11 = 16a - 6b + 6

Answer:

you'd have to know that the corners are at 90 degree angles. as is, it could be a parallelogram

Answer:

Angle R

Step-by-step explanation:

It stated that triangle LMN ≈ triangle QRS

angle L = angle Q

angle M = angle R

angle N = angle S

The reason is (corr. ∠s, similar triangles)

Answer:

Any elements that are in either H or W will be in the union of the sets

Step-by-step explanation:

Anytime that is asking for the union of two sets with the symbol (U) than it is asking you to figure out what elements are in either one of the two sets.

That means the Union would be in either set.

Therefore (Any elements that are in either H or W will be in the union of the sets)

Answer:

the answer isss 62 cm .........

They have to sell D. 75 shirts to make a profit of $300.

The total cost of buying and printing the shirts was $600.

In order to make a profit of $300, they would therefore have to raise:

= Cost + profit

= 600 + 300

= $900

As they are selling each shirt $12, the number of shirts they would have to sell to get to $900 is:

= 900 / 12

= 75 shirts

They would therefore have to sell 75 shirts in order to make a profit of $300.

Answer:

x = [tex]\frac{85}{3}[/tex]

Step-by-step explanation:

From the figure attached,

ΔABC ~ ΔADE

Therefore, by the property of similar triangles corresponding sides of the given triangles will be proportional.

[tex]\frac{AB}{AD}=\frac{AC}{AE}=\frac{BC}{DE}[/tex]

[tex]\frac{AB}{AD}=\frac{BC}{DE}[/tex]

[tex]\frac{12}{20}=\frac{17}{x}[/tex]

x = [tex]\frac{20\times 17}{12}[/tex]

x = [tex]\frac{85}{3}[/tex]

Answer:

x = 2

Step-by-step explanation:

[tex]2log_5 x = log_5 4 \\ \\ log_5 {x}^{2} = log_5 4 \\ \\ \implies \: {x}^{2} = 4 \\ \\ \implies \: x = \pm \sqrt{4} \\ \\ \implies \: x = \pm 2 \\ \\ x = - 2, \: \: x = 2[/tex]

Since, anti-logarithm must be greater than zero.

Answer:

2 1/2

Step-by-step explanation:

When multiplying fractions, you multiply the numerators together and the denominators together.

4 • 5/8

Multiply 4 and 5.

20/8

You can simplify this by dividing both parts by 4

5/2

5/2 is also 2.5

2.5 written as a mixed number is 2 1/2.

This is your answer.

Hope this helps!

Why do this?

Because we want to be able to factor the left hand side into the form p^2, where p is some algebraic expression. This will help us ultimately solve for x.

Currently, the left hand side is x^2+16x which does factor to x(x+16), but that isn't in the form p^2. We want something like (x+1)^2 or (x+2)^2. The general form is (x+k)^2 where k is some fixed constant.

Let's expand out (x+k)^2 using the FOIL rule and we get x^2+2kx+k^2

The x coefficient is 2k. If we cut that in half, we get k. Squaring that result leads to k^2.

So we have this order: 2k cuts in half to k then square it to get k^2

For x^2+16x, we have the x coefficient as 16. That cuts in half to 8, then that squares to 64. We add 64 to both sides

Note how

x^2+16x = 9

x^2 + 16x + 64 = 9+64

(x+8)^2 = 73

From here, we apply the square root to both sides and then subtract 8 from both sides to fully isolate x. You would get two different solutions.

-------------

I recommend you use the FOIL rule to confirm that (x+8)^2 expands out to x^2+16x+64, to help check your work.
