Step-by-step explanation:
2[½ × (20 + 16) × 7]
36 × 7
252
You would need to use the pythagorean theorum which is would be 8 squared +x squared = 15 squared
The expression 4x^2 represents - (4)(x)(x)
P = 2 x ( W+L)
P = 2 x (W + 2W)
p = 2 x 3W
P = 2 x 3(20/3) =40
A set is a well-defined collection of objects. Each object in a set is called an element of the set. Two sets are equal if they have exactly the same elements in them.
A set is a subset of another set if all elements of the set are elements of the set . In other words, the set is contained inside the set . The subset relationship is denoted as A ⊂ B .The relationship of one set being a subset of another is also called inclusion or we can say Set B may have more elements than A does.
Option 4 .Set B may have more elements than A does is the right answer.
