Step-by-step explanation:
A trinomial is an expression that has three terms.
Square trinomial
A square trinomial is simply a perfect square trinomial, and it is represented as:
\mathbf{a^2 + 2ab + b^2 = (a + b)^2}a2+2ab+b2=(a+b)2
Difference of square binomials
This is easily identified because, the terms of the square binomials are perfect squares.
The difference of square binomials is represented as:
\mathbf{a^2 - b^2 = (a + b)(a - b)}a2−b2=(a+b)(a−b)
Sums and difference of cubes
When cubes are added or subtracted, they can be expressed using the following
\mathbf{a^3 + b^3 = (a + b)(a^2 - ab + b^2)}a3+b3=(a+b)(a2−ab+b2) --- sum of cubes
\mathbf{a^3 - b^3 = (a - b)(a^2 + ab + b^2)}a3−b3=(a−b)(a2+ab+b2) --- difference of cubes

Answer:
168 = x
Step-by-step explanation:
mean = u=132
standard deviation =sigma = 20
z score =z=1.8
The formula is
z = (x-u)/ sigma
Substituting what we know
1.8 = (x-132)/20
Multiply by 20
1.8*20 = (x-132)/20 *20
36 = x-132
Add 132 to each side
36+132 = x-132+132
168 = x
Answer:
Step-by-step explanation:
d = 2r => r = d/2 = 16in/2 = 8 inches
V = Ab×h
= π·r²×h
= 3.14·(8in)²×5in
= 1004.8 in³
