Answer:
4x2 + 23x – 72
= (4x - 9)(x+8)
Step-by-step explanation:
Explanation:
The line of reflection is the perpendicular bisector of the segment joining a point with its reflected image.
___
The segment joining a point with its reflection is as short as possible consistent with the requirement that the reflected point be the same distance from the line that the original is. That means it is perpendicular to the line of reflection. Since the distance from that line is the same on either side, the line of reflection bisects the joining segment.
Answer:
38 degrees
Step-by-step explanation:
Angle ABE is 90 degrees, and angle FBE is 52 degrees. 90-52 is 38.
Answer:
3000 people live in brainesville
Step-by-step explanation:
Population of brainville =2000
Grow rate of population per year =10%
10% of population =2000*10/100=200
Grow rate of 5 year=200*5=1000
After 5 year population of brainville is=2000+1000=3000
Answer:
x=20
Step-by-step explanation:
sin¢=cos90-¢
therefore; 3x-15+x+25=90
4x+10=90
4x=90-10=80
x=20
