Question

. Simplify: (2x - 5y)² - (2x + 5y)²​

Answer 1

Answer:

The first and lowest level contains the producers, green plants. The plants or their products are consumed by the second-level organisms—the herbivores, or plant eaters. At the third level, primary carnivores, or meat eaters, eat the herbivores; and at the fourth level, secondary carnivores eat the primary carnivores.

Answer 2

Step-by-step explanation:

${(2x - 5y)}^{2} - {(2x + 5y)}^{2}$

$(4{x}^{2} - 20xy + 25 {y}^{2}) - (4 {x}^{2} - 20xy + 25 {y}^{2} )$

$4 {x}^{2} - 20xy + 25 {y}^{2} - 4 {x }^{2} + 20xy - 25 {y}^{2}$

$0$
