-3+ 4d - 2f + 3d + 6f - 4 - 8

Mathematics
1 answer:
Igoryamba3 years ago
5 0

Answer:

<h2><em><u>7d + 4f - 15</u></em></h2>

Explanation:

-3 + 4d - 2f + 3d + 6f - 4 - 8

= −3 + 4d + −2f + 3d + 6f + −4 + −8

  • Combine Like Terms

= −3 + 4d + −2f + 3d + 6f + −4 + −8

(4d + 3d) + (−2f + 6f) + (−3 + −4 + −8)

7d + 4f + −15

= 7d + 4f - 15

From the top of a 6m house, the angle of elvation to the top of a flappole is across the street is 9 degrees. the angle of depre
Anuta_ua [19.1K]

The height of the flag pole which is described as in the task content is; 8.2m.

<h3>What is the height of the flagpole as described from the top of the 6m house?</h3>

The horizontal distance between the 6m house and the flagpole in discuss can be evaluated by means of the angle of depression and trigonometric identity, tan as follows;

tan 22° = 6/x

x = 6/tan 22 = 14.9m.

Consequently, the horizontal distance from the top of the house to the top of the flagpole is therefore;

tan 9° = y/14.9

y = 14.9 tan 9° = 2.2m

Ultimately, the height of the flagpole is; 6+2.2 = 8.2m.

How do I decide if it’s a real solutions or extraneous solutions?
olga55 [171]

Step-by-step explanation:

So you can check for extraneous solutions by plugging in the 5 and -2 as x.

Plug 5 in as x

5=\sqrt{3(5)+10}\\5=\sqrt{15+10}\\5=\sqrt{25}\\5=5

I'm not sure if this is exactly considered an extraneous solution, but I'm assuming it is, since technically the radical doesn't have a plus/minus in front of it, so it's the principle square root which means it only outputs the positive values. This would mean that the -2 wouldn't be a solution, since the principle square root doesn't output negative values, so it's a function, since if it outputted 2 values, then it wouldn't be a function by definition.

How can i solve this<br> (x+2)(2x+3)<br> step by step please
MrRissso [65]

Answer:

2x² + 7x + 6

Step-by-step explanation:

To solve this polynomial, you need to distribute/multiply, (x+2) with (2x+3).

You would first multiply (x) with 2x and 3. This would give you 2x² and 3x. You would then multiply 2 with 2x and 3. This would give you 4x and 6. You then add the like-terms, which are 3x and 4x, which gives you 7x. This would give you your final expression of 2x² +7x + 6.

(x+2)(2x+3)

2x²+ 3x + 4x + 6

2x² +7x + 6
