Answer:
42
Step-by-step explanation:
Break the trapezoid into three shapes; two 4*3 triangles and one 4/5 rectangle. sole the area for each of the individual shapes and add them all together.
12 + 12 + 20 = 42
The word can be represented as a set and in the roaster form the set of letters is {s, a, l, t}
<h3>What is set?</h3>
A set is a collection of clearly - defined unique items. The term "well-defined" applies to a property that makes it simple to establish whether an entity actually belongs to a set. The term 'unique' denotes that all the objects in a set must be different.
We have given letter:
"salt"
Here, no letter is repeated.
So we can write it as roaster form:
Let's denote the set as S
S = {s, a, l, t}
Number of element in the set = 4
We can make new set from it if the set has only vowels
S(v) = {a}
If set has only consonants:
S(c) = {a, l, t}
Thus, the word can be represented as a set and in the roaster form the set of letters is {s, a, l, t}

Answer:
8 • (b + 1) • (b - 1)
Step-by-step explanation:
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "b2" was replaced by "b^2".
Step by step solution :
Step 1 :
Equation at the end of step 1 :
23b2 - 8
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
8b2 - 8 = 8 • (b2 - 1)
Trying to factor as a Difference of Squares :
3.2 Factoring: b2 - 1
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 1 is the square of 1
Check : b2 is the square of b1
Factorization is : (b + 1) • (b - 1)
Final result :
8 • (b + 1) • (b - 1)
