Find the product. (4m^2 – 5)(4m^2 + 5)
Answers
Answer: 16m^4−25
Step-by-step explanation:
(4m^2−5)(4m^2+5)
=(4m^2+−5)(4m^2+5)
=(4m^2)(4m^2)+(4m^2)(5)+(−5)(4m^2)+(−5)(5)
=16m^4+20m^2−20m^2−25
=16m^4−25

Answer:
The number of new books sold = 10
The number of used books sold (u) = 15
The number of magazines sold(m) = 20
Step-by-step explanation:
Let us assume the number of new books = n
So, the number of used books sold (u) = New books sold + 5 = n + 5
Also, the number of magazines sold (m) = 2 x ( Number of new books sold)
= 2 n
⇒ u = n + 5, m = 2 n
Here, the cost of each new book n- = $12
So, the cost of n new books = n x ($12) = 12 n
the cost of each used book u = $8
So, the cost of u = (n+ 5) used books = n+5 x ($8) = 8 n + 40
the cost of each magazine m = $5
So, the cost of m = (2n ) magazines = 2n x ($5) = 10 n
Also, total earnings = $340
⇒ 12 n + 8n +40 + 10 n = 340
or, 30 n = 300
or,n = 300/30 = 10
Hence the number of new books sold = n = 10
The number of used books sold (u) = n + 5 = 15
The number of magazines sold = m = 2 n = 20

Answer: 10 to the 5th power
Step-by-step explanation: Since 100,000 is a whole number, the exponent on our power of 10 will be positive.
To determine the value of the exponent, we first write a decimal point at the end of 100,000.
Next, we count the number of places we would need to move the decimal point in order to get 1.0.
In this problem, we would need to move the decimal point 5 places to get 1.0 which means that we will have an exponent of 5.
Therefore, 100,000 is equal to 10 to the 5th power.

Let;s find out how many percent is the difference.
=> 48 - 19 = 29.
Next is to solve for the percentage
=> 29 / 48 = 0.60,
=> 0.60 * 100% = 60%
Thus, 19 is 60% lesser than 48.
