Answer:
n < 8
Step-by-step explanation:
Isolate n by subtracting 4 from both sides of the inequality
n < 8
180-(90+36)
Because the other angle is a right angle which is always 90. So, if you take the sum of the numbers you have and subtract that from 180 (because all triangles equal 180) you will get the missing angle.
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
The answer is 3km as there is 9 secs between it and distance = time/3 and 9/3 =3 so distance =3
