Answer:
(b + 3)(4b + 5)
Step-by-step explanation:
Given
4b² + 17b + 15
Consider the factors of the product of the b² term and the constant term which sum to give the coefficient of the b- term.
product = 4 × 15 = 60 and sum = 17
The factors are 12 and 5
Use these factors to split the b- term
4b² + 12b + 5b + 15 ( factor the first/second and third/fourth terms )
= 4b(b + 3) + 5(b + 3) ← factor out (b + 3) from each term
= (b + 3)(4b + 5) ← in factored form
suppose an experiment is rolling a dice and tossing a coin . list the elements of the sample space.
Answer:
S = {1H,2H,3H,4H,5H,6H,1T,2T,3T,4T,5T,6T}
Step-by-step explanation:
A sample space is the set of all outcomes that may come. It consists of all the values that may result in result of an experiment.
In the given problem, we have to find the sample space of rolling a dice and flipping a coin
As the dice has 6 sides and coin has 2 sides
The number of outcomes are: 6*2 = 12
The outcome of dice can either be with heads of coin or tails of coin.
The sample space will be:
S = {1H,2H,3H,4H,5H,6H,1T,2T,3T,4T,5T,6T}

what is the sum of the interior angles of a polygon shown below?
Answer: The sum of the interior angles of a polygon shown in the picture is [tex]540^{\circ}[/tex].
Step-by-step explanation:
The given polygon is a regular pentagon having 5 sides.
The sum of the interior angles of a regular polygon is given by :-
[tex](n-2)\times180^{\circ}[/tex], wherer n= number of sides of the regular polygon.
Since it has 5 sides, then the sum of the interior angles of a polygon would be
[tex](5-2)\times180^{\circ}\\\\=3\times180^{\circ}\\\\=540^{\circ}[/tex]
Hence, the sum of the interior angles of a polygon shown in the picture is [tex]540^{\circ}[/tex].

Answer:
584!
Step-by-step explanation:
Let's see. There is a missing side. Let's call that x. However, we know what the other sides are!
This is how we do it.
We know the largest side's length., 172.
Since we know the other sides, we can subtract their length from 172.
172-57-51-31=33
x=33
So now add the sides!
54+31+66+172+57+30+33+19+51+71\

Step-by-step explanation:
It appears that all choices have the 1st part the same, so we are looking at domains. I recommend drawing the functions without the domain limitations. We know that the linear function is closed so it's inequality is either [tex]\geq[/tex] or [tex]\leq[/tex]. So eliminate B and D. Since the quadratic function continues to the left the inequality sign should be <. So the answer is C

Answer:
[tex]\frac{\pi r^2 }{2}[/tex]
Step-by-step explanation:
pi r ^2 is the formula for a circle, a semicircle is half of that.
The measure of central angle MNL is π radians, and the measure of the entire circle is 2π radians. The ratio of the measure of the central angle to the entire circle measure is . The area of the entire circle is π units2. The area of the sector is π units2.
Answer:
The answer is "The calculated ratio of the central angle to the entire circle is 1:2".
Step-by-step explanation:
Let,
MNL angle [tex]= \pi[/tex]
So, the entire circle is [tex]= 2\pi[/tex]
The ratio of the central angle to the entire circle is:
[tex]\Rightarrow \frac{\pi}{2\pi}\\\\\Rightarrow \frac{1}{2}\\\\[/tex]
Hence, the calculated ratio is = 1:2.

Triangle DEF has vertex coordinates D(0, -3), E(-1,0), and F(-2,-1). It is
reflected across the y-axis. What are the coordinates of D'EF?
The coordinates of D'E'F' after reflection are,
D' = (0, - 3)
E' = (1, 0)
F' = (2, - 1)
We have to given that,
Triangle DEF has vertex coordinates D(0, -3), E(-1,0), and F(-2,-1).
Here, Triangle DEF is reflected across the y-axis.
The rule for a reflection over the y -axis is,
(x, y) → (- x, y)
Hence, the coordinates of D'E'F' after reflection is,
D' = (0, - 3)
E' = (- (- 1), 0) = (1, 0)
F' = (- (- 2), (- 1)) = (2, - 1)

The height of a parallelogram is three times its base. If the area of the parallelogram is 675 square inches, find its base and height.
Which of these choices are correct?
b = 25 in & h = 75 in
b = 75 in & h = 225 in
b = 45 in & h = 135 in
b = 25 in & h = 12.5 in
Answer:
Step-by-step explanation:
let base be x and height be 3x
we know area of parallelogram is
base*height
ie x*3x=675
3x^2=675
x^2=675/3
x^2=225
x= square root of 225
x=15
therefore base =15
height = 45

3) The sum and the difference of the LCM and GCD of two numbers are 312 and 264 respectively. Find the numbers if their sum is 168.
Answer:
The numbers are 72 and 96.
Step-by-step explanation:
LCM + GCF = 312
LCM - GCF = 264
2*LCM = 576
LCM = 576/2 = 288
HCF = 312–288 = 24
The product of two numbers = HCF*LCM
Let the numbers be x and (168-x)
x(168-x) = 24*288 = 6912
x^2–168x+6912 = 0
x = [168 +(168^2 -4*6912)^0.5]/2
= [168 +(28224–27648)^0.5]/2
= [168 + 576^0.5]/2
= (168+24}/2
= 192/2
= 96 and the other number is 168–96 = 72.

Answer:
x = 9
Step-by-step explanation:
→You can use the Pythagorean Theorem to solve:
[tex]a^2+b^2=c^2[/tex]
→The "a," and "b," are the legs, and the "c," is the hypotenuse. In this case, we are already given the hypotenuse as 41, and we are trying to find a leg:
[tex]40^2+b^2=41^2[/tex]
[tex]1600+b^2 = 1681[/tex]
→Subtract 1600 from both sides:
[tex]b^2=81[/tex]
→To get "b," by itself, square root both sides, like so:
[tex]\sqrt{b^2} =\sqrt{81}[/tex]
→81 is a perfect square meaning it has two factors that are identical.
[tex]b = 9[/tex]
