N/4 < -1 — we can multiply both sides with 4, so we dont have to deal with fractions.
N < -4
So, our N goes left from -4 on a number line.
-10x<-100 — divide both sides by 10
-x < -10
x > 10
X is from 10 rightwards.
5x>20 — divide both sides by 5
x > 4
X is rightwards from 4.
He is wrong because if a + b > c it doesn't follow that a^2 + b^2 > c^2
(a + b^2 will always be greater than c^2 but a^2 + b^2 will not always be.

An example:
Right angled triangle with sides 3, 4 and 5:-
3 + 4 > 5 but 3^2 + 4^2 = 5^2
Answer:
52 inches
Step-by-step explanation:
4×13=52 inches
One number is 4 and the second number is 5.
we know that
Volume of a sphere=
in this problem
diameter=3,476 km
so
r=(3,476 /2)
Volume of a sphere=
Volume of a sphere=
km³
Volume of a sphere=
km³
the answer is
the volume of the moon is km³
