A² = b² + c² - 2bcCos A
a² = 11² + 13² - 2(11)(13)Cos(108)
a² = 378.38
a = √378.38
a = 19.45
Answer: 19.45
Answer:
y ≤-1/2 x-1
Step-by-step explanation:
The y intercept is -1
The slope is negative since the line goes down from left to right
The line is y = -1/2 x -1
The line is solid so there is an equals in the inequality
The graph is shaded below the line
y ≤-1/2 x-1
Answer:
There are no like terms.
Step-by-step explanation:
Like terms have the powers and \ or variables. The Coefficients does not have to be the same in like terms.
and are not like terms. They contain a different variable. If they were 9y and 4y (or the other way around with x), then they would have been like terms.
-5 has no other "like terms". All other numbers in the expression have variables, but -5 does not.
There are no like terms in the given expression.
