For this case we must find the solution of the following expression:
![(x + 7) (x + 7) = 0](https://tex.z-dn.net/?f=%28x%20%2B%207%29%20%28x%20%2B%207%29%20%3D%200)
If we isolate a term and we equate to zero, we have:
![x + 7 = 0](https://tex.z-dn.net/?f=x%20%2B%207%20%3D%200)
Subtracting 7 on both sides of the equation we have:
![x + 7-7 = 0-7\\x = -7](https://tex.z-dn.net/?f=x%20%2B%207-7%20%3D%200-7%5C%5Cx%20%3D%20-7)
Thus, the solution of the expression is given by:
![x = -7](https://tex.z-dn.net/?f=x%20%3D%20-7)
ANswer:
![x = -7](https://tex.z-dn.net/?f=x%20%3D%20-7)

Step-by-step explanation:
3021
14 11/18
I got this answer by doing 30 1/9 + 4 1/3= 34 4/9
Now I subtracted 34 4/9 by 19 5/6 to get the answer 14 11/18
TIP: When adding/subtracting/multiplying/dividing mixed numbers change them to an improper fraction first by multiplying the denominator and the whole number then adding the numerator
Step-by-step explanation:
If A=650+135N; and B=585N,
then A+B= 650+135N+585N=650+620N
T=720N+650
Craming last minute can lead to unecessary confusion however most examinars dont allow asking questions during exam
So if asking questions for clarification is allowed. A) is the odd one out
And these options are rather for test taking than learning
