Answer 1

Lose 5.2x yards.

What is the net yardage for these four plays?

is the que correct

Answer 2

19.8x - 11.1y

Explanation:

Given information:

• Gain 25x yards
• Gain 0.9y yards
• Lose 12y yards
• Lose 5.2x yards

"Gain" means to add the value.

"Lose" means to subtract the value.

Therefore, net yardage is:

⇒ 25x + 0.9y - 12y - 5.2x

Collect like terms:

⇒ 25x - 5.2x + 0.9y - 12y

Factor out the common variables x and y:

⇒ x(25 - 5.2) + y(0.9 - 12)

Carry out the operations in the parentheses:

⇒ x(19.8) + y(-11.1)

Therefore, the net yardage is 19.8x - 11.1y
