Answer:
Step-by-step explanation:
The first thing we do to solve this is factor is completley
You can factor out a 4 from the numerator and get
4(3x+4)
The denominator is a difference of squares which means that
(x^2-y^2)=(x-y)(x+y)
which means that 9x^2-16=
(3x-4)(3x+4)
Put these together and get
The 3x+4 cancels out and we get left with
Answer:
Infinate
Step-by-step explanation:
As long as the shape has 8 sides, it is an octagon.
It would be infinate because you can put a stick at an angle of lets say like 24 degrees. Then 24.1, or 24.01, and so on and so forth.
Hope that maybe helped.
Answer:
x=16°, y= 120°
Step-by-step explanation:
Information needed
All angles in the diagram will to 360° equal
The empty angle is (x+8) because of the vertical angles property
Solve for x:
(5x-14)+(x+8)= 90° because it's given that the angle below is a right angle (90°)
(5x-14)+(x+8)= 90°
5x-14+x+8= 90°
5x+x-14+8= 90°
6x-6= 90°
+6 +6
6x= 96°
/6 /6
x= 16°
Solve for y:
x= 16°
90+(5x-14)+(x+8)+(x+8)
90+66+24+24
= 204°
360°-204°= 120°
Answers would be x = -6 , x = -2/3
Answer: Wouldn't That be 15, Since He bought 515, Then spent 500, So 515-500=15 (If its Wrong I'm Sorry)
