Answer:
x=-4.73 x=-1.27
Step-by-step explanation:
(x + 3)^2 - 3 = 0
Add 3 to each side
(x + 3)^2 - 3 +3= 0+3
(x + 3)^2 = 3
Take the square root of each side
sqrt((x + 3)^2) =±sqrt( 3)
(x + 3) =±sqrt( 3)
Subtract 3 from each side
x + 3-3 =-3±sqrt( 3)
x = -3±sqrt( 3)
Approximating to 2 decimal places
x=-1.27 x=-4.73
Hey there! :D
If you already know that two triangles are congruent, (which is given)
then any other part of the triangle can be proved congruent by CPCTC.
Congruent Parts of Corresponding Triangles are Congruent.
I hope this helps!

A relation is a function if you associate exactly one output for every input. This means that, when you choose a value for x, there must be only one correspondent value for y. This only happens in the top-right parabola.
The slope is negative, so the slope is negative. Using the rise over run formula, the slope of the line should be -1.
