Answer:
7.5'
Step-by-step explanation:
Use trigonometry.
Draw it out.
the hypotenuse is 15.
You want to find the adjacent side.
Use cosine (the adjacent over hypotenuse)
cos60=A/15
15cos60=A
7.5=A
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
