Answer:
Substitute 9 for the variable h.Simplify by adding 13 and 9.22 Not-equals 21, so 9 is not a solution to the equation.Step-by-step explanation:
13 + h = 21 for h = 9
1. Substitute 9 for the variable h.
Correct, because the question already giving the value that h = 9.
2. Substitute 21 for the variable h.
False, because in the question it states that h is 9, not 21.
3. Simplify by adding 13 and 21.
False, because they are in different sides.
4. Simplify by adding 13 and 9.
True, the question giving that h is 9. In the left sides, it's 13 + h, by adding 13 and 9, we will get the answer for the left side.
5. 21 = 21, so 9 is a solution to the equation.
False, because in the left side is 13 + h = 13 + 9 = 22.
6. 22 Not-equals 21, so 9 is not a solution to the equation.
True, see the explanation in 5.
Answer:
Substitute 9 for the variable h.
Simplify by adding 13 and 9.
22 Not-equals 21, so 9 is not a solution to the equation.

The point that is marked on the number line is - 0.875.
How to read a number line?According to the number line diagram, the right side after zero is the positive side while the left side before zero is the negative side.
The marked point is before zero, therefore, the marked point on the number line is surely a negative number.
Each step in the number line represents a step of 0.125.
Hence, the marked point represents 7 steps from zero, therefore, the marked point is -0.875.

The solution to the provided expression using the difference of square formula of algebra is a=1.
What is the difference of squares formula?The difference of square says, the difference of the square of two terms is equal to the product of their sum and difference. It can be given as,
a^2-b^2=(a+b)(a-b)
The given expression in the problem is,
[tex]15(2a - 2) = 5(a^2 -1)[/tex]
From the property of difference of square, the above equation can be written as,
[tex]15(2a - 2) = 5[(a +1)(a-1)]\\15\times[2(a - 1)] = 5[(a +1)(a-1)][/tex]
Divide both side of the equation with (a-1) as,
[tex]5\times2 = 5(a +1)[/tex]
Divide both side of the equation with number 5 as,
[tex]2 = (a +1)\\a=2-1\\a=1[/tex]
Hence, the solution to the provided expression using the difference of square method of algebra is a=1.
