Answer:

(2a - b)(4a² + 2ab + b²)

Step-by-step explanation:

8a³ - b³ ← is a difference of cubes and factors in general as

a³ - b³ = (a - b)(a² + ab + b²) , thus

8a³ - b³

= (2a)³ - b³

= (2a - b)((2a)² + 2ab + b² ), that is

(2a - b)(4a² + 2ab + b²)

Solve system of equations:<br> 4l + 8m = 40<br> 5l + 2m = 28<br> Please show steps!
ziro4ka [17]
Answer:

l = 9/2 or 4.5

m = 11/4 or 2.75

Step-by-step explanation:

4l + 8m = 40

8m = 40 - 4I

m = 5 - 0.5l

5l + 2m = 28

5l + 2(5 - 0.5l) = 28

5l + (10 - l) = 28

4l + 10 = 28

4l = 18

l = 18/4 or 9/2

l = 4.5

4l + 8m = 40

4(4.5) + 8m = 40

18 + 8m = 40

8m + 18 = 40

8m = 22

m = 22/8

m = 2.75
