Answer:
Real roots: -4, 1
Complex roots: 2-5i, 2+5i
Step-by-step explanation:
(x²+3x-4)(x²-4x+29)
x²+3x-4=x²+4x-x-4=x(x+4)-(x+4)=(x-1)(x+4)
x²-4x+29 does not have real roots, since delta=16-4×29=-100<0.
However it has complex roots:
(4+/-10i)/2=2+/-5i
So the real roots are: -4 and 1
Complex roots: 2-5i, 2+5i
This answer would be A hope this helps
Step-by-step explanation:
1(
m<1= 62°
2)
m<1=90°
3)
180-70-65=45
m<1= 45°
4)
180-90-30=60
m<1= 60°
<u><em>Answer</em></u>
length: 8 inch and width: 5 inch
<u><em>Explanation</em></u>
Let width be x,
then the length: x + 3
solve:
- As width cannot be negative, width will be 5.
Find for length:
The possible values of N from the given probability parameters is; N equals 15 or 21
<h3>How to Solve Algebra Problems?</h3>
We are told that;
Number of pens in the box = N
Let the number of red pens be x
Thus; number of black pens = x + 3
Thus;
x + x + 3 = N
x = (N - 3)/2
The probability that she will take a black pen followed by a red pen is;
P(she will take a black pen followed by a red pen) = (x + 3)/N * x/(N - 1)
Plugging in he relevant values and solving for N gives ;
Solving for N gives N equals 15 or 21
