Answer:
(4x-5)(4x+5)
Step-by-step explanation:
16x^2 - 25
Rewriting
(4x)^2 - 5^2
We recognize that this is the difference of squares
a^2 - b^2 = (a-b) (a+b)
(4x)^2 - 5^2 = (4x-5)(4x+5)
Answer: 75 meters
Step-by-step explanation: In this problem, we're asked to convert 7,500 centimeters into meters which means we use the conversion factor for centimeters and meters.
Conversion factor ⇒ <em>100 centimeters = 1 meter</em>
Next, notice that we're converting from a smaller unit "centimeters" to a larger unit "meters" and when we convert from a smaller unit to a larger unit we divide by the conversion factor.
So we divide 7,500 by the conversion factor which is 100.
7,500 ÷ 100 = 75
Therefore, 7,500 centimeters = 75 meters.
The first and the second one are true statements.
