Well, what I would do is divide it into two shapes. Cut off the bottom part to make two separate quadrilaterals, and you'd have a square with sides of x. So the area would be x^2. Then, for the remaining piece (rectangle), add the x from the square bit to 5 for one side, and the other side would be x. So you'd have 5x * x, which equals 5x^2. Add the two separate area's together to get the total area, which would give you 6x^2. Hope that helped! :)
Answer:
C) Solution set of{x|X<-3} n {xl x> 5) is an the empty set.
Step-by-step explanation:
Here, the solution set is given as : set of {x| x < -3 } ∩ {x l x > 5)
Now, defining the each set , we get
{x| x < -3 } = ( .... -6,-5,-4 ,-3) = P
and the SET {x l x > 5} = (5,6,7,........ ) = Q
Now, by taking the intersection of two sets,we get
P ∩ Q = NULL SET as they don not have any element in common.
⇒ {x| x < -3 } ∩ {x l x > 5} is an empty set
Hence, solution set of{x|X<-3} n {xl x> 5) is an the empty set.
3x +y = 23 this is the same as y=23-3x
3x - 2y = 8 this is the same as 3x/2-8/2=y, which gives you; y=1,5x-4
so;y=23-3xy=1,5x-4
y=y
23-3x=1,5x-4
23+4=1,5x+3x
27=4,5x
27/4,5=x
x=6
the y is:
3*6+y=23
18+y=23
y=23-18

Answer:
4a-9 ÷ -19
Step-by-step explanation:
(It was easier for me to put it in fractions)
+ 
+ 
(3-a) (a-4) + (5-a) (a-3)
+ + 3 - a · a - 4 + 5 - a · a - 3
+ + 3 - a + 1 - a - 3
1 - a - a
1 - 2a
