-3√48n
I have to solve this using perfect squares, is anyone familiar with those?

-12√3n

Step-by-step explanation:

We want to write this in its simplest form

48 = 16 * 3

√(48) = √16*3

√48 = 4 √3

so we have

-3 * 4 √3n

=

-12√3n

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
