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
4 pairs
Step-by-step explanation:
total is $175
when you buy three pairs of pants you have wasted $90
175-90 equals 85
Answer:
see explanation
Step-by-step explanation:
z - w
= 1 - 3i - (- 2 + 5i) ← distribute parenthesis by - 1
= 1 - 3i + 2 - 5i ← collect like terms
= 3 - 8i
------------------------------------------------------------
z × w
= (1 - 3i)(- 2 + 5i) ← expand using FOIL
= - 2 + 5i + 6i - 15i² [ i² = - 1 ]
= - 2 + 11i + 15
= 13 + 11i
Answer:
22.5
Step-by-step explanation:
Volume is l×w×h
2 × 2.5 × 4.5 = 22.5
