Which expression is equivalent to the area of metal sheet required to make this square-shaped traffic sign?A square shaped traffic sign is shown with length of one side labeled as 8x minus 2.
Answers
square shaped traffic sign. side measure of 8x - 2
A square has 4 equal sides. To find the area of a square, simply square the measure of 1 side.
Area of a square = a²
A = (8x-2)²
A = (8x-2)(8x-2)
A = 8x(8x-2) - 2(8x-2)
A = 64x² - 16x - 16x + 4
A = 64x² - 32x + 4

The algebraic expression is a difference between two terms will be 5y - 7. Thus, the correct option is A.
What is Algebra?
Algebra is the study of algebraic expressions, while logic is the manipulation of those concepts.
An algebraic expression that is created by removing two terms is known as a difference between two terms. Only one of the suggested expressions corresponds to this description:
⇒ 5y - 7
The difference between the terms 5y and 7, which are being subtracted from one another, is represented by this equation.
Thus, the correct option is A.
