Answer:

D or 14 x (2+5)

Step-by-step explanation:

Answer A has 14 as a factor, but that's not what the question is asking for. So, we cannot choose this option.

Answer B has 7 as a factor, so we cannot choose that.

Answer C has 2 as a factor, so we can't choose this option.

Answer D (the correct answer) does not have any factor, so we can choose this.

Therefore, the correct answer is option D. Hope this helps!

Question in picture. Thanks!

2x^2+4x+2
Carry the 2 over to the 3 behind the 4 and multiply so 2times2 is 4. So i new equation is.
X^2+4x+4
Now you have to find the factors of 4 which is 1,4 and 2,2
So now you have to see which one adds up to 4 so 1+4 is 5 so cross that out and 2+2=4.
So the two number is 2 and 2 now you have to bring down the x^2 and the signs.
(X+2) (X+2) and thats your answer

OLga [1]

Answer:

  • m∠J = 76°
  • m∠K = 65°

Step-by-step explanation:

The sum of angle measures is ...

  (7x +13)° +(83 -2x)° = 141°

  5x +96 = 141 . . . . . collect terms, divide by °

  5x = 45 . . . . . . . . . subtract 96

  x = 9 . . . . . . . . . . . divide by 5

  7x +13 = 7·9 +13 = 76 . . . . . find m∠J

  m∠J = 76°

  m∠K = 141° -76°

  m∠K = 65°
