The asnwer is alway true because negative means reverse and positive makes the thing stay the ssame
basically a positive is a blank thing that doesn't do anything while a negative makes change happen (opposite)
with 1 blank thing and an opposite, we get an oposite

so we havve -7 times +11
we can factor out the -1 in -7 so we get
-1 times 7 times 11
we know that 7 times 11=77
then the negative makes it oposite so -1

therefor
if you have -x times +z that equals -1 times (x times z) and since x and z are both positive, they remain so, but the -1 makes it negative

so this statement is always true

(w+14)/(4w+6)=(3)/(4) show work plz
sergey [27]

Answer:

w = -1.44 and w = -14.06

Step-by-step explanation:

That "(3) / (4)" in  (w+14)/(4w+6)=(3)/(4) looks fishy.  Assuming that you really meant 3/4, then we have   (w+14)/(4w+6)=3/4.

Mult. both sides by 4 to remove the fraction:  4(w+14)/(4w+6) = 3.

Multiply out (w+14)/(4w+6):  4w^2 + 6w + 56w + 84.  Combine the w terms, obtaining 4w^2 + 62w + 84.  Then the original equation becomes:

4w^2 + 62w + 84 = 3, or  4w^2 + 62w + 81 = 0.

This is a quadratic equation, with a = 4, b = 62 and c = 81.  The two roots (values of

w) are as follows:

        -62 plus or minus √(62^2-4(4)(81)

   ----------------------------------------------------------

                               8

         -62 plus or minus √(2548)           -62 plus or minus 50.48

w = -------------------------------------------   =  ---------------------------------------

                            8                                                  8

Simplifying, we get w = -1.44 and w = -14.06

Factor.<br> 28 - 4u<br> I don’t know how to factor 28-4u so if anyone can help thank you
Sedaia [141]

Answer: 4(7-u)

Step-by-step explanation:

In order to factor, you have to find the GCF (Greatest Common Factor)

28:1, 28, 2, 14, 4, 7

4:1, 4, 2

The greatest common factor here is 4.

You can factor out 4 from this equation, therefore making it 4(7-u)
