What are the solutions to (x+7) squared = 81

x=2

Step-by-step explanation:

- Take the square root of both sides of the equation so that we can get rid of the squared on the x+7

- The square root of 81 is 9

- so now, the equation is x+7=9

- subtract seven from both sides

step-by-step explanation:

we need to see the graph to know but

strong positive is if it is going up from left to right in a straight diagonal line (like this /)

strong negative is the same but from right to left (like this \)

weak negative is the same as strong negative but its more straight line still right to left

and weak positive is the same as strong positive but more a straight line still left to right though.
