Factor this polynomial expression. 2X2 + 12x + 18

A. 2(x+3)(x+3)

B. 2(x - 3)(x-3)

c. 2(x+3)(x - 3)

D. (2x + 9)(x+2) ​

Answer:

Approximately 1,320 feet.

Step-by-step explanation:

Let one person be x miles from the skycraper, then the other one will be 5 - x miles away from it.

So we have the 2 equations:

tan 4 = h/x

tan 10 = h/(5 - x)        where h is the height of the skyscraper

From the first equation:

h = x tan 4

Substituting in the second equation:

tan 10 = x tan 4 / (5 - x)

5 tan 10 - x tan 10 = x tan 4

x tan 10 + x tan 4 = 5 tan 10

x = 5 tan 10 / ( tan 10 + tan 4)

= 3.58 miles

h = 3.58 * tan 4

= 0.25 miles

= 1320 feet approx.

Answer:

Perimeter = 30 units

m<BCD = 53°

Step-by-step explanation:

Recall: in any parallelogram, consecutive angles are supplementary. Also, the pairs of parallel sides are equal in length.

We would use this knowledge to solve the problem given.

m<ABC = 127° (given)

BC = 10 units

AB = 5 units

✔️Perimeter of the parallelogram = AB + BC + CD + AD

AB = CD = 5 units (pair of parallel sides)

BC = AD = 10 units (pair of parallel sides)

Perimeter = 5 + 10 + 5 + 10

Perimeter = 30 units

✔️m<BCD = 180° - m<ABC (consecutive angles are supplementary)

m<BCD = 180° - 127° (Substitution)

m<BCD = 53°

Answer:

[tex]2.17 \times 10^{-1}[/tex]

Step-by-step explanation:

[tex](7 \times 10 ^{-6}) + 0.26 - (5 \times 10^{-2}) = \frac{7}{10^3} + \frac{26}{10^2}-\frac{5}{10^2}[/tex]

                                              [tex]= \frac{7 + (26 \times 10) - ( 5 \times 10)}{10^3}\\\\=\frac{7 + 260 - 50 }{10^3}\\\\=\frac{217}{10^3}\\\\= 2.17 \times 10^2 \times 10^{-3}\\\\= 2.17 \times 10^{-1}[/tex]

Answer:

The tile feels colder because it's a heat conductor and moves heat rapidly away from your skin which is much warmer than the air temperature. The rug is a heat insulator. The rug slows down the flow of the heat which makes it feel warmer.

Answer:

The Earth is divided into degrees of longitude and latitude which helps us measure location and time using a single standard. Longitude and latitude lines measure the distance from the Earth's Equator or central axis - running east to west - and the Prime Meridian in Greenwich, England - running north to south.

No, the ratios are not equivalent to 2/3. To create an equivalent ratio, you need to multiply both numbers in the original ratio by the same number.

Answer:

25%

Step-by-step explanation:

Simply count the fully shaded squares; there are 22 of them.  Then count the 1/2 filled squares; there are 6 of them.  Combine half squares to make whole squares and you end up with 3 full squares.

Add 22+3 to get 25 -- 25 out of 100 = 25%

Answer:

Similar by SAS

Step-by-step explanation:

If you multiply the two given sides by 3/2 you will get the sides for the large triangle

3/2  * 10 = 30 / 2 = 15

3/2 * 24 = 72 / 2 = 36

Therefore they are similar by SAS postulate for similarity. Notice that the right angle is between the legs of the triangle. That is the main qualification that allows you to use SAS for similarity.

Find the other two angles of both the triangles, if they were similar then the triangles are similar

Answer:

easy that thing needs help

x = 8 × Cos( 72 )

x = 8 × Cos( 90 - 18 )

x = 8 × Sin( 18 )

x = 8 × 0.309

x = 2.472

x = 2.470

x = 2.500

x = 2.5

Answer:

It's D on Edge 2021

I did the assignment

The polynomial that is factored completely is one that can not be factored again is 2g² + 5g + 4. Therefore, option D is the correct answer.

Factorisation of a polynomial is the decomposition of a polynomial into smaller polynomials.

Thus, the polynomial that is factored in completely is the polynomial that can not be decomposed again.

Now,

g⁵ - g = g(g⁴ - 1) (it can be factored)

4g³ + 18g² + 20g = 2g(g + 2)(2g + 5)

24g² - 6g⁴ = 6g²(4g² + g²)

2g² + 5g + 4 cannot be factored again. It is already factored completely

Answer:

40

Step-by-step explanation:

The serving sizes, [tex]x[/tex], of 20, 80, and 120 have a required amount of meat in pounds, [tex]y[/tex], of [tex]y=\frac{1}{10}x[/tex] (the number of pounds of meat is equal to 1/10th the serving size)

However, for the row with a serving size of 40, the number of pounds of meat is equal to [tex]\frac{6}{40}=\frac{3}{20}[/tex] the serving size. Therefore, the serving size of 40 has a different ratio of serving size to pounds of meat than the other ratios.

Answer:

Tony's solution strategy

Step-by-step explanation:

Given the equation that Lucas and Tony trying to solve expressed as: x^2=16x+25

This can be written in standard form as x^2 - 16x - 25 = 0

This can then be factorized using the general formula

x = -b±√b²-4ac/2a where a, b and c are constants

From the given expression;

a = 1, b = -16, c = -15

Hence the best strategy that would have worked based on the explanation is Tony's

Answer:

B

Step-by-step explanation:

Because the equation can be written in the form (x-p)^2+(y-q)^2. So it represents a circle with the radius r=3 and the center of (5,0).

Answer:

C

Step-by-step explanation:

The circle equation (x-a)²+(y-b)²=r² has a radius of r and a center of (a,b).

You can expand your equation from (x-5)²+y²=9 to (x-5)²+(y-0)²=3².

Using this information, you can see that a=5, b=0, and r=3.

Therefore the center is (5,0) and the radius is 3.

Answer:

Lily has 63 points and Nala has 49.

Step-by-step explanation:

Since Nala and Lily are playing a dice game where they score points, and after one round, the ratio of Nala's points to Lily's points is 7 to 9, if Nala has 14 more points than Lily, to determine how many points Lily has se you must perform the following calculation:

9 - 7 = 2

14/2 = 7

7 x 7 = 49

7 x 9 = 63

63 - 49 = 14

Therefore, Lily has 63 points and Nala has 49.

Answer:

3

Step-by-step explanation:

To find the slope of a line perpendicular to a like with a gradient of -1/3, you do the negative reciprocal of -1/3 which would be 3/1 or 3.

Answer:

3

Step-by-step explanation:

let, m = -1/3

and, m1 = x

m * m1 = -1

m1 = -1/-1/3

m1 = 3......

The answer would be number 4, y=3/4x-6.

This is because both of the equations share the same slope of 3/4x.
