I need help with 2 math questions???

Answers

Answer 1

Answer:
#1).
Surely, now that you're in middle school, you know that the volume of a cube is

   (the length of the edge)-cubed
OR
   (length of the edge) x (length of the edge) x (length of the edge) .

The length of the edge of the cube in the picture is 9-ft.
To find the volume of the cube, use the formula that I just reminded you of.

#2).
Twenty minus nine is written as (20 - 9).
Seven is written as (7) .
Their product is written as (20 - 9) x (7) .

To find the value of the expression:

Do the subtraction inside the parentheses: (20 - 9) = 11
So now the whole expression is
   (11) x (7)
Now do the multiplication:
   11 x 7 = 77

Distributive property to express 16+48

Answers

So,

I will un-distribute the GCF of the two numbers.

16(1 + 3)

Distributing we get:
16(1) + 16(3)
16 + 48

After applying the distributive property the expression (16 + 48) is written as,

⇒ 16 (1 + 3)

We have to give that,

A mathematical expression is,

⇒ 16 + 48

Now, apply the distributive property to express the expression as,

⇒ 16 + 48

Since, GCD of (16, 48) = 16

Hence, take 16 as the common number,

⇒ 16 + 48

⇒ (16 × 1) + (16 × 3)

⇒ 16 (1 + 3)

So, it can be written as,

⇒ 16 (1 + 3)

What's the difference between graphing an inequality with a closed dot and one with an open dot?

Answers

open means 'up to, but not including'
closed means 'up to and including'

example
x>3 would have open dot, meaning greater than 3, you can get close to 3, but not 3 like x=3.00000000000000000000001 is a solution, but you cant get to x=3

x>3 would be closed, this would include 3 and up so x=3 is a solution, als x=4, but not less than 3
