x+x+7=63
2x+7=63
2x=56
x=28

The two numbers are 28 and 35
Answer:
x = 5 or x = -11
Step-by-step explanation:
(x+3)²+8=72
x² + 6x + 9 + 8 = 72
x² + 6x -55 = 0
(x - 5) (x + 11) = 0
x = 5 or x = -11
Answer:

Answer:
y= -4/3x - 1/2 is the perpendicular line to y= 3/4x -1/2
Step-by-step explanation:
The slope would be the negative reciprocal of your current slope :)
+3/4 would turn into -4/3 and you wouldnt change the y intercept
hope this helps
