He would factor out 4(x+5)

Step-by-step explanation:

You can't do much until the 4(x+5) is factored out.

Once it is then it'd be 3x-8=4x+20

Then you subtract 3x on both sides and subtract 20 on both sides.

You'd be left with -28=x

Answer:

La persona está a 5 kilómetros con respecto al punto de partida.

Step-by-step explanation:

Considérese que la dirección norte coincide con el semieje +y y que la dirección este coincide con el semieje +x. A continuación, obtenemos las formas vectoriales equivalentes de cada afirmación:

(i) Una persona camina 7 kilómetros hacia el norte:

[tex]\vec r_{1} = 7\,\hat{j}\,[km][/tex]

(ii) Después 3 kilómetros hacia el este:

[tex]\vec r_{2} = 3\,\hat{i}\,[km][/tex]

(iii) Y luego, 3 kilómetros hacia el sur:

[tex]\vec r_{3} = -3\,\hat{j}\,[km][/tex]

El vector resultante de desplazamiento se construye a partir de la siguiente suma de vectores:

[tex]\vec R = \vec r_{1}+\vec r_{2} + \vec r_{3}[/tex] (1)

[tex]\vec R = 3\,\hat{i} + 4\,\hat{j}\,[km][/tex]

Asumiendo que la distancia coincide con el desplazamiento resultante, calculamos la distancia con respecto al punto de partida mediante el Teorema de Pitágoras:

[tex]\|\vec R\| = \sqrt{3^{2}+4^{2}}[/tex]

[tex]\|\vec R\| = 5\,km[/tex]

La persona está a 5 kilómetros con respecto al punto de partida.

Answer:

3 - 57yd²

Step-by-step explanation:

Hey There!

The first step in solving this problem is finding the formula for area of a trapezoid

[tex]A = \frac{a+b}{2} h[/tex]

a = base 1

b = base 2

h = height

For the first one the dimensions are

a = 6

b = 9

h = 4

now we just plug in the values

[tex]A=\frac{6+9}{2} 4\\6+9=15\\\frac{15}{2}=7.5\\7.5*4=30[/tex]

so the area of the first trapezoid is 30 ft²

For the second one the given dimensions are

a = 8

b = 11

h = 6

now we just plug in the values

[tex]A=\frac{8+11}{2} 6\\8+11=19\\\frac{19}{2} =9.5\\9.5*6=57[/tex]

so the area of the second trapezoid is 57 yd²

Use Elimination Method....

2x - y = 2

2x - 2 = y

y = 2x - 2 ----------- equation 1

5x + y = -9

Substitute for y

5x + 2x - 2 = -9

7x = -9 + 2

7x = -7

x = -7/7

x = -1

Substitute for x in equation 1

y = 2x - 2

y = 2(-1) - 2

y = -2 - 2

y = -4

Answer:

(- 1, - 4 )

Step-by-step explanation:

Given the 2 equations

2x - y = 2 → (1)

5x + y = - 9 → (2)

Adding the 2 equations term by term will eliminate the y- term, that is

7x + 0 = - 7

7x = - 7 ( divide both sides by 7 )

x = - 1

Substitute x = - 1 into either of the 2 equations and solve for y

Substituting into (2)

5(- 1) + y = - 9

- 5 + y = - 9 ( add 5 to both sides )

y = - 4

solution is (- 1, - 4 )

Step-by-step explanation:

Given

[tex]Green = 3\\ Orange = 2\\ Red = 5[/tex]

Required

Dependent or independent event

The probability of selecting a green jelly remains unchanged before and after selecting the first orange jelly.

Before selecting the orange jelly:

[tex]P(Green) = \frac{Green}{Total}[/tex]

[tex]P(Green) = \frac{3}{10}[/tex]

After selecting the orange jelly:

[tex]P(Green) = \frac{Green}{Total}[/tex]

[tex]P(Green) = \frac{3}{10}[/tex]

Because the probabilities remain unchanged, the selection of a green jelly is independent of the selection of the first orange jelly.

Answer:

14

Step-by-step explanation:

So if its 224 square feet and the width if 14 feet the length should be 14 also I think lol Here , imagine a square put 224 inside it for the area , then put down 14 on top and bottom because its the width , multiple 14×14=56+140=196+14=210+14=224 And the last 14's are the length which u have to add Im not sure if that made any sence lol but I hope it did .

Answer:

Step-by-step explanation:

sin Ф equal the opposite leg of the triangle dividend by the hypotenuse

sin Ф = opp / hyp

the problem gave you the Ф (the angle 7°)

and the length of the hypotenuse (the walking surface 60 inches)  

You want to use the inches since the question wants to know how many inches off the floor is the end of the walking surface

sin 7 = opp / 60          solve for opp

60 × sin(7) = opp             use your calculator,   I don't have one handy

Answer:

  B  10 cm by 15 cm

Step-by-step explanation:

The volume of a pyramid is given by ...

  V = 1/3Bh

where B is the area of the base, and h is the height.

Solving for B, we find ...

  3V/h = B

  3(1000)/20 = B = 150

The product of the base dimensions must be 150 cm².

The choices are ...

  A  10×5 = 50

  B  10×15 = 150 . . . . could be

  C  30×0.5 = 15

  D  30×11 = 330

10 cm by 15 cm could be the dimensions of the vase base.

Answer:

its 5325.76190476

or 5325.8 if you want to round it

Step-by-step explanation:

a) The two triangles that are congruent are △RUQ and △SPR.  b) The length of UQ is 7√2 cm. The length of PQ is 2√30 cm.

(a) The two triangles that are congruent are △RUQ and △SPR. This is because they have the same side lengths: RU=RP=7 cm, SU=SP=9 cm, and ∠RPQ=∠SPR=90°.

(b) To calculate the length of UQ, we can use the Pythagorean Theorem on △RUQ. The Pythagorean Theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. In this case, the hypotenuse is UQ, and the other two sides are RU and RP.

[tex]UQ^2[/tex] = [tex]RU^2[/tex] + [tex]RP^2[/tex]

[tex]UQ^2[/tex] = [tex]7^2[/tex] + [tex]7^2[/tex] = 98

UQ = √98 = 7√2

Therefore, the length of UQ is 7√2 cm.

To calculate the length of PQ, we can use the Pythagorean Theorem on △PQR. The Pythagorean Theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. In this case, the hypotenuse is PQ, and the other two sides are RP and QR.

[tex]PQ^2[/tex] = [tex]RP^2[/tex] + [tex]QR^2[/tex]

[tex]PQ^2[/tex] = [tex]7^2[/tex] + [tex]9^2[/tex] = 120

PQ = √120 = 2√30

Therefore, the length of PQ is 2 30 cm.
