4 0

Answer:

Step-by-step explanation:

hello :

note :

for all x in ℝ :   1) sin(x+2kπ) = sinx         ...k in Z   2)  sin(-x) = -sinx

in this exercice :

sin(-4π-x)= sin(-x) = -sinx   because : -4π = 2(-2)π  (form  : 2kπ  when : k=-2)

Sam has 12 black and white photos and 18 color photos.he wants to put the photos in equal rows so each row has either black and
yawa3891 [41]
The question is asking us to determine the number of rows in which Sam can arrange his 12 black and white and 18 color photos. Sam wants to put them in the equal rows so that each row has either black and white photos only or color photos only. We have to find the GCF ( the Greatest Common Factor ) of 18 and 12. GCF ( 18, 12 ) = 6. So there should be 6 photos in each row if they have to be equal ( the equal number of photos in every row ). 18 = 6 * 3 and 12 = 6 * 2. Therefore the number of the rows is : 3 + 2 = 5. Answer: Sam can arrange his photos in 5 rows<span>. </span>

Help asap!! How many triangles can be constructed with sides measuring 7cm,6cm, and 9cm?
NikAS [45]

Answer:

C. One

OR

B. more than* one

Step-by-step explanation:

This answer actually depends on a couple of aspects, which the question is a bit unspecific about. It fails to clarify whether mirrored images/congruent triangles count as one or more than one. If there is any missing information, please quickly include it under the "Ask For Details."

HOW you solve this question is rather easy.

As you should know, there are dedicated theorems and equations for the majority of elements within Algebra, Calculus, Geometry, and sciences.

In this situation, you'd use the GEOMETRY triangle inequality theorem: IF the sum of any two sides is greater than or equal to the final side value, you've got a triangle.

Sides: 7cm, 6cm, 9cm.

<em>7cm + 6cm  =  13cm; 13cm > 9cm</em>

<em>7cm + 9cm = 16cm; 16cm > 6cm</em>

<em>9cm + 6cm = 15cm; 15cm > 7cm</em>

<em></em>

As you can see, you have all three possibilities with good prospects. Now, this is the complicated part. If Mirror Images/ Congruent Triangles are in the equation, all triangles will be congruent due to SSS (Side, Side, Side) configuration. This eliminates the possibilities for THREE total options and narrows it to ONE, because all triangles will be congruent.

The answer ultimately depends on the complete context of the question & the material you are currently covering.

If you've yet to learn of all the configurations and mirrored images, your answer is B: more than one

If you've ALREADY learned this and are currently utilizing the process, your answer is C. One

Personally, I'd lean more towards B., as most questions this simple don't take mirrored images or congruence into effect.

How to solve 3 + 2x = 5 + 4x
notka56 [123]

Hello!

First, let's subtract 4x from both sides.

3-2x=5

We subtract 3 from both sides.

-2x=2

We divide both sides by -2.

x= -1

I hope this helps!
