Answer:
see explanation
Step-by-step explanation:
This is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
16
= ( 4
)² ⇒ a = 4
1 = 1² ⇒ b = 1
Hence
16 - 1
= (4 )² - 1²
= (4 - 1)(4 + 1)
4 - 1 ← is also a difference of squares and factors as
(2x² - 1)(2x² + 1)
Thus
16 - 1
= (2x² - 1)(2x² + 1)(4 + 1 )
Answer:
gabby is correct

4=-4
fasle
(2,8)
6(2)+8=4
12+8=4
20=4
false
(1,2)
6(1)+2=4
4+2=4
6=4
false
(1,-10)
6(1)+-10=4
6-10=-4
-4=-4
true
ANSWER IS D
Answer:
120 millimeters or 0.12 liters
Step-by-step explanation:
To solve this question :
- we have to convert liters to millimeters
- multiply the serving of coca by the number of people that consumed the coca
- subtract the answer gotten from the step above from 2 litters
1 liter = 1000 millimeter
2 liters = 2 x 1000 = 2000mm
8 people drank cocoa = 8 x 235 = 1880mm
Amount of cocoa left over = 2000 - 1880 = 120mm or 0.12 liters
