Answer:
31 = 2⁵ -1
31 = 16²- 15²
Step-by-step explanation:
As we know that
2¹=2
2²= 4
2³= 8
2⁴= 16
2⁵=32
So
32 = 2⁵
By subtracting 1 in bot sides
32-1 = 2⁵ -1
31 = 2⁵ -1
So
2⁵ -1 = 31
By comparing with
p= 5
As we know that
15²= 225
16² = 256
16²- 15² = 256-225 = 31
16²- 15² = (16+15)(16-15)
31 = (16+15)(16-15)

Step-by-step explanation:
she crochets at a rate of 1/15 per day but if she can manage to get 3/15 done within maybe a day or two, then she will get 1 blanket done in 5 to 10 days. then 3 blankets could take anywhere from 15 - 30 days which leaves 30 days to spare. this probs isn’t what ur looking for but i have a pointttt
Answer: x² - x - 12
Step-by-step explanation: When multiplying two binomials together, we can use the F.O.I.L. method.
<em>First, Outer, Inner, Last</em>.
We take the product of the first terms which is x² plus the product of the outer terms which is -4x plus the product of the inner terms which is 3x plus the product of the last terms which is -12.
So we have x² - 4x + 3x - 12.
Simplifying from here by combing the middle terms, we have x² - x - 12.
Pay very close attention to your positives and negatives as you F.O.I.L. because this is the area where most mistakes occur.
4 x 35 = $140
$140 + 9 = $149
$200 - $149 = $51
Yes, she has enough to buy a $50 wheelbarrow.
