Answer:

Using the "AC Method" I got (w - 2) (w + 9)

Step-by-step explanation:

Answer:

(w−2)(w+ 9)

Step-by-step explanation:

Grouping

Step 1:

Use the sum-product pattern

w²  + 7 − 18

w² + 9 − 2 −18

Step 2:

Common factor from the two pairs

w²+ 9 − 2 − 18w

( w+ 9) − 2( w+ 9)

Step 3:

Rewrite in factored form

(w + 9) − 2( w+ 9)

(w−2)(w+9)

Answer:

193.69

Step-by-step explanation:

The answer is M

Step-by-step explanation:

Cosine: this is the length of the side right next to the angle divided by the longest side/ hypotenuse.

Tan: this is the length of the side opposite of the angle divided by the side directly adjacent/ next to the angle.

In this case, cosine would be 6/10 which Is also 3/5. the angle right next to 6 is Angle M

Answer:

x = -180

Step-by-step explanation:

0 = 0.65x + 117

-117 = 65x/100

cross-multiply to solve for 'x':

65x = -11700

x = -11700/65

x = -180

Answer:

384, 216, 290, 192, 384

1446, 1 roll

Step-by-step explanation:

For rectangular boxes, calculate the sum of each side, then multiply it by two.

Box 1: 2(18 x 5) + 2(18 x 4) + 2(5 x 4) = 364

Box 3: 2(11 x 8) + 2(8 x 3) + 2(3 x 11) = 290

Box 5 is a cube (all sides equal), so you can find 1 side's area and multiply it by 6.

Box 5: 6(8 x 8) = 384

For triangular boxes, calculate the edges, then find the triangular area using area = 0.5(base x height).

Box 2: (15 x 3) + (9 x 3) + (12 x 3) + 2(0.5)(9 x 12) = 216

Box 4: 2(13 x 2) + (10 x 2) + 2(0.5)(10 x 12) = 192

Total: 364 + 290 + 384 + 216 + 192 = 1446

Rolls of wrapping paper:

Area of 1 roll = 30 x 60 = 1800

Since 1446 is less than 1800, you only need 1 roll of wrapping paper.

La respuesta esta abajo

Step-by-step explanation:

Un triángulo es un polígono con tres lados y tres ángulos.

Se dice que dos triángulos son proporcionales si la razón de sus lados correspondientes está en la misma proporción.

de la pregunta, el lado AB es proporcional a DF, AC es proporcional a DE y BC es proporcional a FE

Por lo tanto, dado que ambos triángulos son proporcionales, entonces:

DE / DF = AC / AB

x / 10 = 21/15

x = (21/15) * 10 = 14

Answer:

i. 5 people

ii. Mean number of pets = 2

Step-by-step explanation:

i. From the information given in the question, the number of people surveyed by Edward is 5.

The first person has no pet, the second has 1 pet, the third has 2 pets, the fourth has 3 pets and the fifth has 4 pets.

ii. The mean number of pets is the average number of pets among the people.

The mean number of pets = [tex]\frac{sum of the number of pets}{number of people}[/tex]

                                     = [tex]\frac{0 + 1 + 2 + 3 + 4}{5}[/tex]

                                     = [tex]\frac{10}{5}[/tex]

mean number of pets  = 2

The mean number of pets is 2.

Answer:

Amount of water in each balloon = 300 milliliter

Step-by-step explanation:

Given:

Amount of water used in balloon = 6 liter

Number of water balloon  = 20 balloon

Find:

Amount of water in each balloon

Computation:

Amount of water used in balloon = 6 x 1000

Amount of water used in balloon = 6,000 milliliter

Amount of water in each balloon = Amount of water used in balloon / Number of water balloon

Amount of water in each balloon = 6,000 / 20

Amount of water in each balloon = 300 milliliter

Answer:

It's D

Step-by-step explanation:

you just look at the end it's says -14. u have to see what numbers should multiply in order to get negative 14, you can use -2 and 7, or -7 and 2, but you have to see what numbers from the -14 will add up -5 because u have five in there, therfore -7+2 equals -5.* This only happens if you have 1 behind the x^2.

Answer:

E) 37

Step-by-step explanation:

The total measurement for the angle ABC is 90 as it is a right angle.

Add your known angles together and substract from 90 to get your unknown.

90 - 21 - 32 = 37

Answer:

E. Subtract 21 and 32 from 90, x=37

Step-by-step explanation:

Since there are 90 degrees in a right angle, we can find the missing angle by adding the two angles we have together and then subtracting the sum from 90.

89 if you pay 11$ to go to the museum for Justin 1$

Step-by-step explanation:

100 - 11 = 89.

Answer: (x-3)(2x+1)(8)

Step-by-step explanation: First factor out the 8 to get (8)(2x^2-5x-3). So now we have what number multiply out to -6 (ab) and add up to -5. -2 and -3 work out so we manipulate the equation like (8)(2x²-2x-3x-3). Factor out 2x in the first term and -3 in the second and keep going.
