4x + 10 = 2x + 20
4x - 2x = 20 - 10
2x = 10
x = 5

The straight one, 4th row.
Step-by-step explanation:
linear graph forms a straight line.
y=mx+c
Well, if 4 muffins cost $5.24, then we can do 5.24 ÷ 4 = 1.31 to know that one muffin costs 1.31. Now we can do 1.31 x 5 = 6.55 to know 5 muffins cost 6.55.

Answer:
2(2x + 5)(2x - 5)
Step-by-step explanation:
2(2x + 5)(2x - 5)
= (4x + 10)(2x - 5)
= 8x² - 20x + 20x - 50
= 8x² - 50
