we need a rock garden work a perimeter of 18ft area 18ft what is the length and width
​

Answers

Answer:

P = perimeter

A = area

l = lenght

w = width

P = 2 x l + 2 x w

A = l x w

18 ft = 2 x l + 2 x w

18 ft² = l x w

Input l = 6 ft w = 3 ft

18 ft = 12 ft + 6 ft = 18 ft

18 ft² = 6 ft x 3 ft = 18 ft²

Answer:

l = 6 ft

w = 3 ft

Step-by-step explanation:

let the length be l and breadth be b.

perimeter = 2(l +b)

18 = 2(l+ b)

9 = l+ b

b = 9-l .... eq - 1

area = l× b

18 =l ( 9-l)

18 = 9l - l²

l²- 9l + 18 = 0

l ² -3l - 6l +18 = 0

l (l -3) -6 ( l -3) = 0

(l - 6 ) ( l-3) = 0

length (l). = 6 or 3 ft

then breadth = 9-l = 9-3 or 9-6

= 6 or 3 ft

We need a flower garden with a perimeter of 18 feet and an area of 18 square feet.what is the Length and width
​

Answers

Answer:

length is 6feet and width is 3 feet

Step-by-step explanation:

Area of the garden = LW

Perimeter of the garden = 2(L+W)

L is the length

W is the width

Given

Area = 18 square feet

Perimeter = 18feet

Substitute

18 = LW ... 1

18 = 2(L+W)

9 = L+W .... 2

From 2;

L = 9-W

Substitute into 1

18 = (9-W)W

18 = 9W-W²

W²-9W+18 = 0

W²-6W-3W+18 = 0

W(W-6)-3(W-6) = 0

W-3 = 0

W = 3 feet

Since L = 9-W

L = 9-3

L = 6feet

Hence the length is 6feet and width is 3 feet

Evaluate −nz−z2−2z when n=3. Simplify your answer.

Answers

Answer: n=

−z2−5

z

Step-by-step explanation:

Let's solve for n.

(−n)(z)−z2−2=3

Step 1: Add z^2 to both sides.

−nz−z2−2+z2=3+z2

−nz−2=z2+3

Step 2: Add 2 to both sides.

−nz−2+2=z2+3+2

−nz=z2+5

Step 3: Divide both sides by -z.

−nz

−z

=

z2+5

−z

Answer:

-z^2-5z

Step-by-step explanation:

To evaluate a polynomial at a given value, we substitute the given value for the variable and then simplify using order of operations. We are given n=3, so we substitute 3 for n in the polynomial −nz−z2−2z and simplify as follows.

−nz−z2−2z

−(3)z−z2−2z

−3z−z2−2z

XYZ has vertices X(3. -4), Y(6, 5), and Z(8, -2).find the coordinates of the vertices of X'Y'Z after a dilation of XYZ by a scale factor of 4

Answers

I believe you would just multiply each value in the coordinates by 4.
So they would become:
X(12,-16), Y(24,20), and Z(32,-8)

The coordinates of the vertices of X'Y'Z after a dilation of XYZ by a scale factor of 4 is X'(12, -16), Y'(24, 20) and Z'(32, -8).

What is scale factor?

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).

The basic formula to find the scale factor of a figure is expressed as,

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.

Given that, XYZ has vertices X(3, -4), Y(6, 5), and Z(8, -2).

Scale factor = 4

Here, X(3, -4)→4(3, -4)→X'(12, -16)

Y(6, 5)→4(6, 5)→Y'(24, 20)

Z(8, -2)→4(8, -2)→Z'(32, -8)

Therefore, the coordinates of the vertices of X'Y'Z after a dilation of XYZ by a scale factor of 4 is X'(12, -16), Y'(24, 20) and Z'(32, -8).

Thirty-eight cities were researched to determine whether they had a professional sports​ team, a​ symphony, or a​ children's museum. of these cities, 21 had a professional sports team, 20 had a​ symphony, 17 had a​ children's museum, 14 had a professional sports team and a​ symphony, 10 had a professional sports team and a​ children's museum, 10 had a symphony and a​ children's museum, and 6 had all three activities. How many of the cities surveyed had only a professional sports​ team?

Answers

Answer:

3 of the cities surveyed had only a professional sports​ team.

Step-by-step explanation:

We solve this question treating these as Venn sets.

I am going to say that:

Set A: professional sports team.

Set B: Symphony.

Set C: Children's museum.

We start building from the intersection of these three.

6 had all three activities.

This means that [tex]A \cap B \cap C = 6[/tex]

10 had a symphony and a​ children's museum,

This means that:

[tex](B \cap C) + (A \cap B \cap C) = 10[/tex]

[tex](B \cap C) + 6 = 10[/tex]

[tex](B \cap C) = 4[/tex]

That is, 4 have only the symphony and children's museum, while 6 have all three.

10 had a professional sports team and a​ children's museum

[tex](A \cap C) + (A \cap B \cap C) = 10[/tex]

[tex](A \cap C) + 6 = 10[/tex]

[tex](A \cap C) = 4[/tex]

14 had a professional sports team and a​ symphony

[tex](A \cap B) + (A \cap B \cap C) = 14[/tex]

[tex](A \cap B) + 6 = 14[/tex]

[tex](A \cap B) = 8[/tex]

21 had a professional sports team

This means that:

[tex](A - B - C) + (A \cap B) + (A \cap C) + (A \cap B \cap C) = 21[/tex]

In which (A - B - C) represents the cities which had only a sports team. So

[tex](A - B - C) + 8 + 4 + 6 = 21[/tex]

[tex](A - B - C) = 3[/tex]

3 of the cities surveyed had only a professional sports​ team.
