Answer:
4 - 7g
Step-by-step explanation:
Combine like terms: 5 - 9 - 7g = -4 - 7g (answer)
N³ - 2n² - 15n = 0
"n"
n (n² + 2n - 15) = 0
n = 0
n² + 2n - 15 = 0
Δ = (2)² - 4(1)(-15)
Δ = 4 + 60 = 64
n' = (-2+8) / 2 = 6/2 =3
n'' = (-2-8) / 2 = -10/2 = -5
Solution:
S {-5 , 0 , 3 }
Answer:
2000
Step-by-step explanation:
(4x5) x 100
The expression that represents the number of reams of paper produced in the second year is 4.704 x
(option d)
<h3>What is the expression that represents the reams produced in the second year. </h3>
The quantity of paper produced in the first year is written in scientific notation. Scientific notation is used to compress larger numbers into smaller numbers.
In order to write a number in scientific notation, the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.
For example, The number 5 x 10³ is equivalent to 500
Paper produced in the second year = paper produced in the first year x 5.6
(8.4 x
) x 5.6 = 47.04 x 
4.704 x 
= 4.704 x
