Answer:
a number 12
Step-by-step explanation:
duh bro
Step-by-step explanation:
80+60+x+51= 180
191+x= 180
x= -11
3.5% of 600...turn percent to a decimal..." of " means multiply
0.035 * 600 = 21 <=== 21 phones are likely to be defective
To figure out the interior angles you multiply the number of sides minus 2 by 180 so for a triangle there are 3 sides so you minus 2 to get 1 multiply it by 180 and you get 180 which is the interior angles of a triangle so to do this one you minus 2 from 6 to get 4 multiply it by 180 and you get 720 degrees
Answer:
(-5+√5)/2 and (-5-√5)/2
Step-by-step explanation:
For a general quadratic equation of the form ax²+bx+c = 0
The value of x can be gotten using the general formula expressed as:
x = -b±√b²-4ac/2a
Now given the function
f(x) = x² + 5x + 5
We can get the zeros of the function in its radical form by simply applying the formula above.
From the equation given;
a = 1, b = 5 and c = 5
Substituting this values in the formula we have:
x = -5±√5²-4(1)(5)/2(1)
x = -5±√25-20/2
x = -5±√5/2
x = (-5+√5)/2 and (-5-√5)/2
The zeros of the function in its simplest radical form are
(-5+√5)/2 and (-5-√5)/2
