Answer: C
Step-by-step explanation:
On the left side, there are 2 triangles and 6 2's, so this equals 2x+12.
On the right side, there are 4 triangles and 2 2's, so this equals 4x+4.
Meaning 2x+12=4x+4.
12=2x+4
2x=8.
Answer:
Step-by-step explanation:
a) Area of white square = side *side = 8 * 8 = 64 sq.mm
Area of 4 white square = 4 * 64 = 256 sq.mm
compound shape
length = 3 cm = 30 mm
Width = 2 cm = 20 mm
Area of compound shape = length *width = 30 * 20 = 600 sq.mm
Area of the shaded part of the compound shape =
Area of compound shape - Area of 4 white square
= 600 - 256
= 344 sq.mm
b) Perimeter of compound shape = 2*(length + width)
= 2*(30 +20)
= 2* 50
= 100 mm
De Morgan's law: (A∩B)' = A'∪B'
(S₁∩P)' = S'₁ ∪ P'
S'₁={P} ∪ {S₂}
P' ={ S₁} ∪ {S₂}
S'₁ ∪ P' ={P} ∪ {S₂} ∪ { S₁} ∪ {S₂}
(S₁∩P)' = S'₁ ∪ P' = SPACE
