Pls HELPPPP HURRYYY PLSS
IceJOKER [234]

Answer:

A. 1 unit

Step-by-step explanation:

A cube has the same dimensions on each side, and the unit is 1 unit cube, none of the other options match.

You can easily rule out, B & D. That leaves you with A & C, and A makes the most sense, since 1 cubic unit would be the volume, and this question is only asking for the side length.

Good luck, hopefully, this helped!

If B equals 7 what is the value of the expression 2 + (10 - B )?
avanturin [10]

We just need to <u>plug in 7 for B! </u>

Let's do it !

2 + (10 - 7)

<em>We always start with the parenthesis first ! It's just a rule in math :) </em>

10 - 7 = ?

10 - 7 = 3

Now we have ...

2 + 3

2 + 3 = 5

Your final answer is 5!

I hope I helped :) Just comment if you have any questions and remember to vote me "brainliest" if you like my answer !!!

Find the domain and range of the relation: (-8,8),(-8,7),(-8,6),(-8,5). Then determine whether the relation is a function.
Andrej [43]
The domain is {-8}
The range is {5,6,7,8}
The relation is not a function as the domain value -8 maps to multiple values. All domain values in a relation needs to map to exactly one range value for it be a function.
