Answer:
first multiply the numbers in side the parentheses, make the number an improper fraction(check for cross multiplication) then multiply.
Step-by-step explanation:
<span>A sample of n=8 has an ss=50 if these were a population the ss value of the population would be
(50/8) of the sample = 6.25 of sample. Usually, ss value of the population i s calculated by dividing ss by the sample values. This is the way to calculate ss value of the population.</span>
By factoring the quadratic equation, 4 porcelain vases can be glazed with 20 pints of glaze. (Correct choice: B)
<h3>How much vases can be glazed with a certain amount of pints of glass?</h3>
Herein we have a quadratic equation that models the quantity of pints as a function of the number of vases, we need to solve the quadratic equation for v to find the required quantity. The complete procedure is shown below:
v² + v = 20 Given
v² + v - 20 = 0 Compatibility with addition / Existence of the additive inverse / Modulative property
(v + 5) · (v - 4) = 0 x² - (r₁ + r₂) · x + r₁ · r₂ = (x - r₁) · (x - r₂)
The result must be a positive number and, thus, the maximum number of vases must be equal to 4. By factoring the quadratic equation, 4 porcelain vases can be glazed with 20 pints of glaze. (Correct choice: B)

Answer:
k² + 10k + 24
Step-by-step explanation:
First, the square has side length k. Now in rectangle,
l= k+6
b= k+4
Ar. of rectangle= l×b
Eq.
(k+6)(k+4)
opening bracket,
k² + 6k + 4k + 24
k² + 10k +24
