Answer:
D
Step-by-step explanation:
Since the constructed line is a perpendicular bisector of the line AB, then
AC = BC ← substitute values
4x + 12 = 2x + 18 ( subtract 2x from both sides )
2x + 12 = 18 ( subtract 12 from both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Hence
AB = 2AC = 2(4x + 12) ← substitute x = 3
AB = 2(12 + 12) = 2 × 24 = 48 → D
The two other points would be (13,1) and (13,13) because the square tile is 12 inches on each side.
1.) answer: 5
Steps subtract 3 from both sides 8-3 is 5 so x is 5
2.) answer: -12
Because the 4 is positive you subtract it on the other side to cancel it out and -4 +-8 is -12 so x is -12
the 2 equations that need to be solved are [3x+5] and x-1. If you need the answer to what x is you'd solve it by evening out the problems. so first add one to both so you'd have 3x+6=x then you'd take the 3x and subtract it from both sides making it 6=-2x. Then divide 6 by negative 2 making it -3=x.
