Answer:
36in²
Step-by-step explanation:
<h3>Area of the White Region: </h3>
A = l * w
The rectangle is 3 by 2.
A = 3 * 2
A = 6
The white part of the rectangle is 6in².
<h3>Area of the blue region:</h3>
A = l * w
The rectangle is 6 by 7.
A = 6*7
A = 42
The blue part of the rectangle is 42in².
<h3>Area of the shaded region:</h3>
[area of the blue part] - [area of the white part]
42 - 6 = 36
The area of the shaded region should be 36in².
The product of the given expression is -120. Option A is correct
<h3>Product of negative numbers.</h3>
Given the expression below as shown;
−5⋅(−3)⋅(−8)
Since the product of two negative number is equal to positive, then;
−5⋅(−3)⋅(−8) = -8(5*3)
Simplify the result to have:
-8 * 15
find the final product
-8 * 15 = -8(5+10)
-8 * 15 = -40 - 80
-8 * 15 = -120
Hence the product of the given expression is -120

Answer:
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.
