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.
See it is < and not ≤ so we don't include -4
put a circle around -4 but don't shade it in
to get there, move 4 units left from 0
then we see x is less than -4
so shade to the left of the circle
Answer: whats the question here if you wanna know how many boys there are there should be 12

Answer:
C and D
Step-by-step explanation:
The area of a rectangular raised garden bed for growing beets is given by the expression 
The area of the rectangle is

Thus,

or

The length of the mat is greater than its width. Since

then

Options A and B are false, options C and D are true.
All the numbers in each equation are identical, just the letter changed, which doesn't affect the equation.
Because they are both the same, the answers would be the same, so the difference would be 0.
