R=7 because you would do -49 divided by -7
In any equation there is a variable (usually x). In a quadratic equation there is a lot involved.
-B (+or-) sqrt of b^2 - 4 x A x C
________________________ divide it by
2 x A
There is usually an original equation that looks like: Ax^2 + Bx + C = 0 Use the variables from the equation to the left to fill the upper equation. (You can also look up a better formula if confused).

Answer: -1=6-7/5
Step-by-step explanation:
Answer: Option A. |-7| = 7
Solution:
The distance is a positive value, then we must not take in account the sign, and using:
|a| =-a if a<0
with a=-7
|-7| = -(-7)
|-7| = 7
