Answer:

5( 4x-5)(4x+5)

Step-by-step explanation:

80x^2 – 125

Factor out a 5

5( 16 x^2 - 25)

Inside the parentheses is the difference of squares

5 ( (4x)^2 - 5^2)

We know the difference of squares is  (a^2 - b^2) = (a-b) (a+b)

5( 4x-5)(4x+5)

Andrews [41]

Answer:

7 1/12 bushels of sweet corn per acre of land

= 85/4 ÷ 3

= 85/4 × 1/3

= 85 / 12

= 7 1/12

Average loss = 7 1/2 bushels of sweet corn per acre of land
