Start with the second expression. That factors easily into (8x-3)(8x+3).
Since 64x^2 + 48x + 9 has no negative signs, I'd bet that the common factor is (8x+3). Divide <span>64x^2 + 48x + 9 by that to verify.

41% and 0.41 im not sure for the last one but hope im right !!
Answer:
A)50°F = 10°C
B)75°C = 167°F
C)-40°C = -40°F
Step-by-step explanation:
A) 50°F = 10°C
Formula
(50°F − 32) × 5/9 = 10°C
B) 75°C = 167°F
Formula
(75°C × 9/5) + 32 = 167°F
C) -40°C = -40°F
Formula
(-40°C × 9/5) + 32 = -40°F
<span>The answer to this question would be: 2.5 minute
In this question, when Sam started to run Leo was already 100 meters away. But Sam runs 105m/min which was faster than Leo(65m/min).
Then the time needed for Sam to catch up Leo should be:
time= distance / (Sam speed-Leos peed)
time= 100m/ (105-65m/min)
time= 100m/(40m/min)= 2.5min
