Answer:
1+4=5 haha
Step-by-step explanation:
Well, the y axis is the one that goes up and down, so it's pretty clear that it's flipped over that. After it gets reflected over the y axis, the -2 changes into 2 (so -2 is multiplied by -1) as it is the x coordinate, making the center (2,5). After that, you'd want to get the y value down by 4 to match it up with (2,1), meaning that the second option down is right!

Answer:
1.1 Factoring: x2-44
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 44 is not a square !!
