The first picture represents the elements in B that are not (also) in A. So, we want the set difference of B and A:
For the second picture, we can work like this: if we take all the elements belonging to A, we only need to add the bottom-right part, which is the intersection of B and C. So, we can express the blue part as
-6.5x + 3 < 19 - 2.5x
-6.5x + 2.5x < 19 - 3
-4x < 16
-4x/-4 > 16/-4
x > -4
Answer: not a solution
Step-by-step explanation:
Y= x+1. (1,0)
Substitute 0 for y and 1 for x and solve
0=1+1
0=2
Therefore the ordered pair is not a solution
Answer:
80 in.²
Step-by-step explanation:
The total surface area of the pyramid is the sum of the area of the base and the areas of the 4 triangular sides.
Square: area = s²
Square: side = 4 in.
Triangular side: area = bh/2
Triangular side: base = 4 in.; height = 8 in.
Area of the base: s² = (4 in.)² = 16 in.²
Total area of the 4 triangular sides: 4 × bh/2 = 2bh = 2 × 4 in. × 8 in. = 64 in.²
Surface area = 16 in.² + 64 in.² = 80 in.²
IM TRYNA GET THIS TOOOOO :(
