hundred and hundredth are way different 11.75 I think it would be tho
Step-by-step explanation:
Answer:
C -2 or 1
Step-by-step explanation:
So from the equation you have x^2-x-1=-2*x+1
x^2-x-1+2*x-1=0
x^2 +x -2 =0
D= 1^2 -4*(-2)= 1+8=9
x = (-1+-3)/2
So x is either (-1+3)/2=2/2=1
or (-1-3)/2=-2
Answer: i've heard about it but i'm not too much into it
Answer:
Step-by-step explanation:
Notation
We need some notation to make talking about sets easier. Consider,
A
=
{
1
,
2
,
3
}
.
We can divide the above figure into two rectangles MNSR and OPQS.
The dimension of rectangle MNSR is 3 x 4 (Since, MR = 3 and MN = 4).
So, area of rectangle MNSR = 3* 4 = 12 square units.
Similarly dimension of rectangle OPQS is 3 x 1 because
PQ = MR - NO = 3 - 2 = 1
SQ = RQ - MN = 7 - 4 = 3.
So, area of OPQS = 3* 1 = 3 square units.
Hence, the area of polygon MNOPQR = Area of rectangle MNSR that is 12 square units + Area of rectangle OPQS that is 3 square units.
= 12 + 3
= 15 square units.
Hope this helps you!
