Answer:
17. a) (4x - 8)(6x+ 7); b) 20x - 2
18. a) (2x² + 3x - 5)(2x + 3); b) 4x² + 10x - 4
Step-by-step explanation:
Question 17
a) Area
Area = length × width
A = (4x - 8)(6x+ 7)
b) Perimeter
Perimeter = 2 (length + width)
P = 2(4x - 8 + 6x + 7) = 2(10x - 1) = 20x - 2
Question 18
a) Area
A = (2x² + 3x - 5)(2x + 3)
b) Perimeter
P = 2(2x² + 3x - 5 + 2x + 3) = 2(2x² + 5x - 2) = 4x² + 10x - 4
12 muffins for 4.80 is the better deal.
Explanation: the ratio of $ to muffin for the first deal is .40:1 which is 40 cents per muffin. Compare this to the second deal’s ratio, .45:1, or 45 cents per muffin, which is higher. Thus, the first deal is better
