you were overcharged 4.52 on your cell phone bill 3 months in a row. the cell phone company says that it will add -4.52 to your
Digiron [165]

<u>Answer:</u>

No, incorrect. It should be -13. 56 unit

<u>Step-by-step explanation:.</u>

I am overcharged  4.52 unit on my cell phone 3 months in a row.

So, net amount I am overcharged = 4.52 \times 3 unit

                                                           = 13.56 unit

So, in the next bill there should be an adjustment of - 13.56 unit. But, here it is given - 13.28 unit only. So, this is incorrect.

Can anyone help with this?
Morgarella [4.7K]

Answer:

111 degrees

Step-by-step explanation:

the total degrees in a hexagon is 720 degrees.

the known angles add up to 379, so there is 341 degrees left.

angle KFE is 105 degrees because it adds up to 180 degrees with GFK.

angle LAD is 130 degrees because it adds up to 180 degrees with BAD.

130+105=230, so there is now 111 degrees left and that is angle x

Is X +3 a factor of 2X squared minus 2X -12
Fantom [35]

Answer: No, x+3 is not a factor of 2x^2-2x-12

========================================================

Explanation:

Let p(x) = 2x^2 - 2x - 12

If we divide p(x) over (x-k), then the remainder is p(k). I'm using the remainder theorem. A special case of the remainder theorem is that if p(k) = 0, then x-k is a factor of p(x).

Compare x+3 = x-(-3) to x-k to find that k = -3.

Plug x = -3 into the function

p(x) = 2x^2 - 2x - 12

p(-3) = 2(-3)^2 - 2(-3) - 12

p(-3) = 12

We don't get 0 as a result so x+3 is not a factor of p(x) = 2x^2 - 2x - 12

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

Let's see what happens when we factor p(x)

2x^2 - 2x - 12

2(x^2 - x - 6)

2(x - 3)(x + 2)

The factors here are 2, x-3 and x+2
