Ok so this is a difference of 2 perfect squares
1=1^2
49c^2=(7c)^2
to factor you remember
a^2-b^2=(a+b)(a-b) so
1^2-(7c)^2=(1+7c)(1-7c)
5.99 per pound * 1.75 pounds purchased = $10.4825. If you round it, she spent $10.48
Answer:
am not sure but
Step-by-step explanation:

<u>This is a GP with the first 6 terms:</u>
<u>Sum of the distances:</u>
- 32 + 16 + 8 + 4 + 2 + 1 = 63 m
