Use the grouping method to factor this polynomial.
3+2x2 +7 x + 14
Answer:
7 ( x + 3 )
Step-by-step explanation:
Use order of operations to multiply first.
3+2x2 +7 x + 14
3+4 +7 x + 14
Now group like terms.
3+ 7x + 4 + 14
Add like terms
7x + 21
Find the two multiples of 21.
7x + 7 x 3
Now factor out the 7.
7( x + 3 )
Stefan sells Jin a bicycle for $125 and a helmet for $18. The total cost for Jin is 130% of what Stefan spent originally to buy the bike and helmet. How much did Stefan spend originally? How much money did he make by selling the bicycle and helmet to Jin?
PLEASE TELL ME AN ANSWER, THIS TEST IS DUE IN 5 MINUTES.
Answer: The selling cost for Stefan bicycle = $114 and
the selling cost of a helmet = $18.
The total cost for Jin is 120% of the money spent.
Let us assume purchasing cost of a bicycle = $x.
Purchasing cost of a halmet = $y.
For bicycle
120% of x is $114
=> 1.20 × x = 114
Dividing both sides by 1.20, we get
x=$95.
For helmet.
120% of y is $18.
=> 1.20 × y = 18.
Dividing both sides by 1.20, we get
y = $15.
Therefore, Stefan spent originally to buy a bike $95 and $15 to buy a helmet.
$114 - 95 = $19
$18 - 15 = $3.
Therefore, he made $19 by selling the bicycle and $3 by selling the helmet to Jin.
Hope this helps have a awesome night/day❤️✨

What is the explicit rule for the sequence:
11, 22, 44, 88...
Answer:
Geometric Progression is the explicit rule for the given sequence: 11, 22, 44, 88...
First term (a) = 11
Common ratio (r) = 22/11 = 44/22 = 88/44 = 2
Formula used in Geometric Progression is :---
[tex]\boxed{a_n = a {r}^{(n - 1)}}✓\\ [/tex]
where, 'n' is the required term
1) The region enclosed by the x-axis, the line x=3 and the curve y = sq. Rt x is rotated about the x-axis. What is the volume of the solid generated? *
Using the disk method, the volume would be
[tex]\displaystyle \pi \int_0^3 (\sqrt x)^2 \,\mathrm dx=\pi \int_0^3 x\,\mathrm dx=\frac\pi2 x^2\bigg|_0^3=\boxed{\frac{9\pi}2}[/tex]
That is, you split up the solid into disks of some small height ∆x, and each disk has radius at point x equal to the distance (√(x)) from the axis of revolution (the x-axis, y = 0) to the curve y = √(x). The volume of such a disk is then π (√(x))² ∆x. Take the sum of these volumes to get the total volume, then as the heights get smaller and smaller, replace ∆x with dx and the sum with the integral.
In this exercise we have to use the knowledge of the integral to calculate the volume of the disk that will correspond to:
[tex]V= \frac{9\pi }{2}[/tex]
That is, you split up the solid into disks of some small height ∆x, and each disk has radius at point x equal to the distance (√(x)) from the axis of revolution (the x-axis, y = 0) to the curve y = √(x). The volume of such a disk is then π (√(x))² ∆x. Take the sum of these volumes to get the total volume, then as the heights get smaller and smaller, replace ∆x with dx and the sum with the integral. Using the disk method, the volume would be:
[tex]\pi \int\limits^3_0 {(\sqrt{x})^2} \, dx = \pi \int\limits^3_0 {x} \, dx = \frac{\pi x^2}{2} = \frac{9 \pi }{2}[/tex]

The required solution is as follows,
(1) the given number is an irrational number. Option D is correct.
(2) π is an irrational number. Option D is correct.
Rational numbers are numbers that can be structured in the form of the fraction of integers. Eg- 5/6, 2/3 etc.
Here,
(1)
Given number,
0.101001000100001…
Since the given number has repeating decimals so, it is an irrational number.
(2)
π
Since π also an irrational number, because it value, is nonterminating and repeating.
Thus, the required solution is as follows,
(1) the given number is an irrational number. Option D is correct.
(2) π is an irrational number. Option D is correct.

In many cities, when someone doesn't pay off an entire fine, the city will add a monthly fee until they do. Watch the video from Last week tonight with john Oliver. Then, imagine Ali gets a $150 ticket for speeding. This time, though, the city adds a $35 fee every month until the ticket is fully paid. Use the table and graph to show what the fine will be, and how much Ali will have saved, after each month. How long will it take to pay off the ticket, and how much will it end up costing in total?
Information : Ali makes $50 in savings a month. Also i need the months of the fee and ali to go up to 12 months. thank youuu

Find measure of angle PQS
Answer:
ANGLE PQS = 45°Step-by-step explanation:
angle SRT = 180 - 70 = 110
thus angle QSR = 180 - 20 - 110 = 50
BY Angle sum property
angle PQS = 180 - 85 - 50 = 180 - 135 = 45

Answer:
B
Step-by-step explanation:
A right triangle is formed by the ground, the side of the house and the ladder.
The hypotenuse is the ladder
let the side of the house be h
Using the sine ratio in the right triangle formed, then
sin77° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{h}{22}[/tex] ( multiply both sides by 22 )
22 × sin77° = h , then
h ≈ 21.44 ( to the nearest hundredth )
The ladder reaches 21.44 ft up the side of the house

Answer:
I think y=-5 , x = 3
Answer:
y = 5/3x - 5
Step-by-step explanation:
Slope = rise / run
The distance between two points is 5 up and 3 right. Hence, 5/3x is the slope.
-5 is where the line crosses the y axis, making it the y-intercept.
