Answer:
A value that satisfies this equation is called a root, zero or solution of the equation!! We have three ... Solve each by factoring. 1) x2 + 4x -5 = 0 ... Follow the explanation and sample problem to review completing the square.
Step-by-step explanation:
If

is true, then

is false, which in turn means

is true.
If

is false, then

is true, and so

is false.
So, because

in both cases, the statement is a tautology (always true).
If you were to put this in a table, you would have one column each for

. In the first column (

) you can think of

as an independent variable that can only take two values, true and false. In the next column (

), you would negate the value in the previous column. And so on.
It should roughly look like this:
p ... ~p ... ~(~p)
T ... F ... T
F ... T ... F
It is not a sum, it is a product.
3 times x = 24 (write equation)
3x = 24 (isolate x by dividing the coefficient, 3, on both sides)
/3 /3
x = 8 (this i your answer)
Therefore 3 times 8 gives you 24.
Answer:
61.93°
Step-by-step explanation:
sin x=15/17
=0.8824
sin-1 0.8824
=61.93°
