Answer:
1
Step-by-step explanation:

just substitute -2 for x
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
Answer:
No
Step-by-step explanation:
The angles of a triangle must always add up to 180 degrees.
90 + 60 + 60 = 210 degrees.
Therefore it would not be possible to draw a triangle with these values.
A set of numbers is said to be Pythagorean triple if the sum of the squares of the lesser numbers equal the square of the remaining number,
A. 28² + 45² = 2809 ; 53² = 2809 ; EQUAL
B. 16² + 63² = 4225 ; 65²= 4225 ; EQUAL
C. 13² + 84² = 7225 ; 85² = 7225 ; EQUAL
D. 11² + 61² = 3842 ; 62² = 3844 ; NOT EQUAL
The answer is letter D.
