<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.
Add up all together 7+5+8+4+6=30 then take away 5 equaling 25 over 30 in simplest would be 5/6
Correct question:
Evaluate and simplify the expression when a = 3 and b = 2,
given expression = 3b-2(1 - b)a - 2
Answer:
3b-2(1 - b)a - 2 at the given values is 10.
Step-by-step explanation:
Given;
3b-2(1 - b)a - 2
The expression is simplified as;
3b-2(1 - b) a - 2 = 3b - 2a(1 - b) - 2
= 3b - 2a + 2ab - 2
When a = 3 and b = 2; then, substitute these values in the simplified expression above;
3b - 2a + 2ab - 2 = 3(2) - 2(3) + 2(3 x 2) - 2
= 6 - 6 + 12 - 2
= 10
Therefore, 3b-2(1 - b)a - 2 at the given values is 10.
