Step-by-step explanation:
Cognitive tools are tools that help to engage and facilitate cognitive processing and learning. Like language is a cognitive tool.
Here, the following is the best example of a cognitive tool
A: The concept pi (π) in a geometry class
Step-by-step explanation:
G(x) = 2/3 x - 6 switch x and y around and solve for y.
y = 2/3 x - 6
x = 2/3 y - 6
x + 6 = 2/3 y
3/2 x + 9 = y
Answer is : 8v^3+ 14v^2+11v+3
For cubic feet
Solution
Formula : volume base area x height
So base area = 4v^2 +5v+3
Height = 2v+1
So multiply
Volume =(4v^2+5v+3) x(2v+ 1)
The rest is below
Answer:
Step-by-step explanation:
