The answer is 4
you just subtract 3 from 7
<u>A cross section parallel to the base is a square measuring 4 cm by 4 cm
</u>
<u>Step-by-step explanation:</u>
Here we have to select the correct statement regarding a cross section of the cube :
<u>A cross section parallel to the base is a square measuring 4 cm by 4 cm
:</u>
Since , every side of a cube is same . Any cross section of a cube must be parallel to a square base . Hence, correct statement .
<u>A cross section parallel to the base is a rectangle measuring 4 cm by greater than 4 cm
:</u>
Since , every side of a cube is same . Any cross section of a cube must be parallel to a square base . Here, base is rectangle . We don't have a rectangle base in cube . Not correct statement.
<u>A cross section perpendicular to the base through the midpoints of opposite sides is a rectangle measuring 2 cm by 4 cm:</u>
Since , every side of a cube is same . Any cross section of a cube must be parallel to a square base . Here, base should be square not rectangle . So , Not correct statement.

Answer:
-9 ≤ y ≤ 8
Step-by-step explanation:
look at the endpoints of the segment; (7, 8) and (-2, -9)
the y-values represent the range and they go from -9 to 8, inclusive
Answer: B) It represents the product of two irrational numbers and is equivalent to an irrational number.
Step-by-step explanation:
1. By a definition an irrational number cannot be written as a simple fraction.
2. Keeping this information on mind:
(Cannot be written as a simple fraction. It is an irrational number).
(Cannot be written as a simple fraction. It is an irrational number).
3. When you multiply this irrational number, you obtain:
4. 
is an irrational number.
5. Therefore, the answer is the option B,
