Answer:
The difference between area of pyramids is 125 sq.m.
Step-by-step explanation:
Length of base = 10m
Breadth of base = 10 m
Slant height = 15 m
Area of pyramid = Area of 5 bases
Area of pyramid = 
Area of pyramid = 400 sq.m.
Now the length of base is increased to 15
Length of base = 15m
Breadth of base = 10 m
Slant height = 15 m
Area of pyramid = Area of 5 bases
Area of pyramid =
Area of new pyramid = 525 sq.m.
Difference between area of pyramids=525 sq.m. - 400 sq.,. = 125 sq.m.
Hence The difference between area of pyramids is 125 sq.m.

The upside down U means intersection
A intersect B intersect C is where all 3 circles overlap.
Sum up all the numbers to get 50
P (a intersect b intersect c) = 6/50 = 3/25
4.) 2(x-1)+3= 2x+1
Distribute the 2, multiply the 2 by x and -1.
2*x= 2x (all you need to do is put 2 in front of x)
2*-1= -2
2x-2+3= 2x+1
Combine like terms.
2x+1=2x+1
Subtract one on both sides.
2x=2x
Divide by 2 into both sides.
x=1
We can check this by plugging it in.
2(1-1)+3= 2(1)+1
2(0)+3= 2+1
0+3=3
3=3 <== this works
I hope this helps!
