area of court=
=(1.98+3.96+0.76)×6.2
=40.87 m^2
area of service box
=(3.96)×5.18/2
=10.256 m^2
pr=area of service court/area of court
=10.256/40.87
=25.095
hope it helps you!!
Answer:
A
Step-by-step explanation:
Given
(3x² - 11x - 4) - (2x² - x - 6)
Distribute both parenthesis, noting the second is distributed by - 1
= 3x² - 11x - 4 - 2x² + x + 6 ← collect like terms
= x² - 10x + 2 ← this is a quadratic with 3 terms, thus trinomial → A
