Answer:
16b^4-9
Step-by-step explanation:
Factoring gives us 16b^4+12b^2-12^2-9. Simplifying gives us the answer which is 16b^4-9
Answer:
[tex]16b^4-9[/tex]
Step-by-step explanation:
When multiplying binomials, we can use a method called FOIL (First-Outside-Inside-Last).
For [tex](t_1+t_2)(t_3+t_4)[/tex], let:
[tex]t_1\implies \text{First Term},\\t_2\implies \text{Second Term},\\t_3\implies \text{Third Term},\\t_4\implies \text{Fourth Term}[/tex]
In the FOIL method, the steps go:
[tex]\text{\textbf{F}irst: Multiply the first and third terms (first term of each binomial)},\\\text{\textbf{O}utside: Multiply the first and fourth terms},\\\text{\textbf{I}nside: Multiply the second and third terms},\\\text{\textbf{L}ast: Multiply the second and fourth terms (last term of each binomial) }[/tex]
Given [tex](4b^2+3)(4b^2-3)[/tex], we have:
[tex]\text{First: }4b^2\cdot 4b^2,\\\text{Outside: }4b^2\cdot -3,\\\text{Inside: }3\cdot 4b^2,\\\text{Last: }3\cdot -3,\\\rightarrow 16b^4-12b^2+12b^2-9[/tex]
Combine like terms:
[tex]\boxed{16b^4-9}[/tex]
According to his GPS, it will take Lanny 1 hour to travel 40 miles. Which expression shows how to determine the speed in miles per hour?
40 miles ÷ 1 hour
1 hour ÷ 40 miles
1 mile ÷ 40 hours
40 hours ÷ 1 mile
Answer:
40 ÷ 1
Step-by-step explanation:
Speed = Distance : Time
Speed = 40 ÷ 1
If u={a,b,c,d}and p={b,d,e}find p(bar at the top)
Answer:
{a , c}
Step-by-step explanation:
first find u intersection p
n(U n P ) = {a , b , c , d} n {b , d , e}
={d , b}
intersection means element or values which lies in both the sets
now to find p complement
note : p( bar at the top ) is read as p complement
p complement = n(U) - n(U n P)
={a , b , c , d} - {d , b}
={a , c}
n(U) -n(U n P) means the elements which is only in n(U ) but not in n(U n P)
Answer:
a,c

What is the volume of the composite figure shown? Use 3.14 for π.
Answer:
25.12
Step-by-step explanation:
the formula of a cone is pi r^2 * h/3
r = radius and h = height
the radius is 2 and the height is 3
and the question says use 3.14 instead of pi so
we have
3.14 * 2^2 * 6/3
2*2 or 2^2 = 4
3.14 * 4 * 6/3
6/3 = 2
3.14 * 4 * 2
4*2 = 8
and 8 * 3.14 is 25.12

You are renting a car that charges a $30 fee plus 40 cents a mile. The rate of change is $30.
True or False?
Hi there!
»»————- ★ ————-««
I believe your answer is:
False.
0.40 is the rate of change.
»»————- ★ ————-««
Here’s why:
As mentioned in the scenario, the car company charges a $30 fee which is flat. The '30' is the base for the total cost. The car company also charges 40 cents for every mile driven. This means that the company would charge a 40 cents for a mile driven. 40 cents would be the rate of change, not $30.⸻⸻⸻⸻
Side Note:
An equation that represents the situation could be:
[tex]C = 0.40m + 30[/tex]
'C' is the total cost for renting the car.
'm' is the number of miles the car is driven.
⸻⸻⸻⸻
»»————- ★ ————-««
Hope this helps you. I apologize if it’s incorrect.
Rule 1: Multiply by 2, then add one third starting from 1. Rule 2: Add one half, then multiply by 4 starting from 0. What is the fourth ordered pair using the two sequences? (5, 10) (four and two thirds, 42) (21, 170) (two and one third, 2)
Find the missing dimensions
Answer:
short base: 6 yards
long base: 8 yards
Step-by-step explanation:
Our understanding of your figure is shown below.
The question says the "shortest side" and the "width" have the same dimension. If the "width" is a reference to "height 6 yards", then it seems the "shortest side" is 6 yards. Since the slant sides are longer than the height, the "shortest side" is also the "short base."
The short base is 6 yards.
__
The long base overhangs the short base by 1 yard on either end, so it is a total of 2 yards longer than the short base. It it 6+2 = 8 yards long.
The long base is 8 yards.
Hope this is correct, if not then feel free to let me know. I'm sorry in advance if it is incorrect.
One staple weighs 31 milligrams. If a box of staples holds 250 staples, how many grams of staples does the box hold?
A: 6.75
B: 7.75
C: 67.5
D: 77.5
E: 7,750
If you get this right i will give you the brainliest!
Answer:
7.75
Step-by-step explanation:
1 mg = 0.001 g
31 mg * 0.001 = 0.31 grams per staple
0.31 g * 250 = 7.75 grams per 250 staples
Answer:
b) 7.75
Step-by-step explanation:
convert 31 milligrams to grams = .031 grams
250 x .031 = 7.75 grams

Answer:
6 2/3 = x
Step-by-step explanation:
24 1/14 + 8 3/7 = (x ÷ 1 1/9) * 5 5/12
Add on the left by getting a common denominator
24 1/14 + 8 3/7*2/2 = (x ÷ 1 1/9) * 5 5/12
24 1/14 + 8 6/14 = (x ÷ 1 1/9) * 5 5/12
32 7/14 = (x ÷ 1 1/9) * 5 5/12
32 1/2 = (x ÷ 1 1/9) * 5 5/12
Changing to improper fractions
(2*32+1)/2 = (x ÷ 10/9) * (12*5+12)/12
65/2 = (x ÷ 10/9) * (65)/12
Multiply each side by 12/65
65/2 * 12/65 = (x ÷ 10/9) * (65)/12*12/65
6 = (x ÷ 10/9)
Copy dot flip
6 = x * 9/10
Multiply by 10 /9
6 * 10/9 = x * 9/10 * 10/9
60/9 =x
20/3 =x

Answer:
(you'll have to read the explanation)
Step-by-step explanation:
There are 8 lines from 1 to 2, so plotting 1 1/2 (or 1.5) is right in between. I'm not sure how to add the picture back into the explanation, but I will try my best to explain. You want to plot your point for 1 1/2 4 lines after the 1. For the 2 1/4, you want to plot your point on the second line from the 2. Let me know if it doesn't make sense!
Answer: See the attached image below
1 1/2 is located at the exact midpoint between 1 and 2.
2 1/4 is located 2 tickmarks to the right of 2.
===================================================
Explanation:
Think of 1/2 as 4/8
The number 1 1/2 is the same as 1 4/8
So we start at 1 and move 4 tickmarks to the right to get at the exact midpoint (note there are 8 tickmarked spaces between any two whole numbers).
This places us exactly at the midpoint between 1 and 2.
-----------------
To plot 2 1/4, we will effectively plot 2 2/8 since 1/4 = 2/8
We start at 2 and then move 2 tickmarks to the right to arrive at 2 2/8
