The length of a side of a square is 4x-1 express the area of the square in terms of x
Accepted Solution
A:
The area of the square in terms of x is 16x² - 8x + 1Step-by-step explanation:The formula of the area of a square is A = L², where L is the length of its side∵ The length of a side of a square is 4x - 1∴ L = (4x - 1)∵ The area of the square is A = L²∴ A = (4x - 1)²To solve bracket power 2Find (1st term)²Find (1st term × 2nd term × 2)Find (2nd term)²Add all the answersThe first term is 4x and the second term is -1∵ (4x)² = 16x²∵ (4x)(-1)(2) = -8x∵ (-1)² = 1∴ (4x -1)² = 16x² + -8x + 1∴ (4x -1)² = 16x² - 8x + 1∴ A = 16x² - 8x + 1The area of the square in terms of x is 16x² - 8x + 1Learn more:You can learn more about the area of figures in brainly.com/question/4599754#LearnwithBrainly
