I think it means like explain what are variable is. Only if your finding a variable: explain how you got the answer to that variable. Hope I helped!

Hi hopefully this helps you!
Step-by-step explanation:
To find the area of a circle you can use the formula A = πr^2
The radius of a circle is just the diameter divided by 2. In this case we know the diameter is 3, so the radius is 1.5
A = π(1.5)^2
= 7.07
Because this is a semicircle, divide this area by 2
= 3.53429 in^2
Add up the area of this semi circle with the area of the rectangle
A = (3.53429) + (3x4)
= 15.53429 in^2
To find the circumference/ perimeter of a circle use this formula C = 2πR
C = 2π(1.5)
= 9.42478 inches
Again because this is a semicircle, divide by 2
= 9.42478 / 2
= 4.71239 inches
To find the perimeter of this entire shape add up the circumference of the semicircle and the rectangle's sides and bottom
P = 4.71239 + 4 + 4 + 3
= 15.71239 inches
So the final answer would be
A = 15.53 squared inches
P = 15.71 inches
Hope this helps! Best of luck in your studies <3
Example-A statistical question is a question that can be answered by collecting data that vary. For example, “How old am I?” is not a statistical question, but “How old are the students in my school?” is a statistical question.
Answers- A, C, D and E
Answer:
The answer to your question is -3 and 2
Step-by-step explanation:
If an equation is factored, to find the roots, just equal each term to zero.
(x + 3)(x - 2) = 0
Equal each term to zero
x₁ + 3 = 0 x₂ - 2 = 0
Solve for x
x₁ = -3 x₂ = 2
The solutions to this quadratic equation are -3 and 2.
