Answer:
44
Step-by-step explanation:
2x² - 2x - 5 = 0 is written in standard form ax^2 + bx + c = 0.
By looking at the formula, we can see that;
a = 2
b = -2
c = -5
Now, we can substitute these variables into the equation we are given and solve.
= b² - 4ac
= -2^2 - 4(2)(-5)
= 4 - 4(-10)
= 4 - (-40)
= 4 + 40
= 44
Best of Luck!
Answer:
n = 1.92
Step-by-step explanation:
Multiply both sides of the equation by 3.2
Simplify both sides of the equation.
n = 1.92
<em>good luck, i hope this helps :)</em>
I am pretty sure it's 44 degrees.
