Answer:
B. The solution is valid because all steps to solve the inequality for F are correct.
Step-by-step explanation:
F - 32 ≤ 0
Add 32 to both sides of the equation to have;
F -32 + 32 ≤ 0 + 32
F ≤ 0 + 32
F ≤ 32
It can be observed that to solve for F, the steps are correct. Thus the solution is valid. Therefore, the correct choice in the given question is the solution is valid because all steps to solve the inequality for F are correct.
I believe it would be the 3rd one.
12. She could label it "Polygons with at least one right angle."
13. Draw two vertical lines that cut the rectangle into three vertical sections that are all about the same size (since the horizontal line is already drawn, there will be six sections). The lines should be about 1/3 and 2/3 of the way through the rectangle.
14. Choices B and C. a is parallel to c and b is parallel to d.
