a. –2x + 5
b. 2x – 5
c. –2x – 5
d. 2x + 5

Answer 1

answer

B,2x-5

Explanation:

• $4x - 20x + 25 \\ 4 {x }^{2} - 10x - 10x + 25 \\ 2x(2x - 5)( - 5)(2x - 5) \\( 2x - 5)(2x - 5) \\ so \: area \: of \: squre \: garden \: is \: (2x - 5)(2x - 5) \\ thena \: side \: is \: equal \: to \: 2x - 5$
• in 4x
