Answer:
(2 x +1) ( x + 1) = 2 x² + 3 x + 1
Step-by-step explanation:
The steops used to find the product of (2 x + 1) (x + 1) are
=( 2 x )× x + (2 x) × 1 + x + 1
= 2 x² + 2 x + x + 1
= 2 x² + 3 x + 1
You can have one that is 1x12, another that is 2x6, and another that is 3x4. Hope that helps!
Store B has the lowest price.
Store A
2lb = $8.44
1lb = $4.22
0.5lb = $2.11
(1lb + 0.5lb) 4.22 + 2.11 = 6.33
1.5lb = $6.33
Store B
1.5lb = $5.85
1 m = 1000 mm so due to that 0,13 m = 1000 * 0,13m = 130mm
