Which of the following equations is a quadratic equation? HELP ASAP
Answer:
(x+5)(x+25)=5
Step-by-step explanation:
When simplified, if you foil the left side of the equation, you get:
x^2+30x+125 = 5
Simplified, you get:
x^2+30x+120 = 0
A quadratic by definition is a polynomial with the highest degree of 2, which means the highest exponent should be a two. In our case, it is. So therefore, (x+5)(x+25)=5 is the answer.
Answer:
Option 1
Step-by-step explanation:
(x + 5)(x + 25) = 5 is a quadratic equation. It can be verified upon expansion.
=> x² + 30x + 125 = 0
=> Quadratic equations are of the form Ax² + Bx + C = 0
=> Hence it is a quadratic equation

➠ The Pythagorean theorem was put forward by the Greek mathematician and philosopher named Pythagoras.
The Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other sides.

Half a number added to the number gives 240.What is the number?
Answer:
Step-by-step explanation:
Let number be "n".
Half a number added to the number = 240
This means
0.5n + n = 240
1.5n = 240
Divide both sides by 1.5
n = 240/1.5 = 160
Photo Necessities produces camera
cases. They have found that the cost,
c(x), of making x camera cases is a
quadratic function in terms of x.
The company also discovered that it
costs $16 to produce 2 camera cases, $18
to produce 4 camera cases, and $48 to
produce 10 camera cases.
Here is the cost function used to
represent this situation in terms of the
number of camera cases produced:
(x) = 0.5x2. 2x + 18
Find the total cost of producing 8 camera cases.
Answer:
A graphing calculator can do quadratic regression on the given points. It tells you the cost function is
.. c(x) = (1/2)x^2 +8x +10
Then c(12) = 178
The cost function predicts the total cost of producing 12 camera cases is $178.

The sum of two numbers is 6 and the sum of their squares is 90. Find the numbers.
Let's set up the variables for the two numbers --> 'a' , 'b'
Now let's set up some equations based on the given information:
sum of two numbers is 6 --> a + b = 6sum of their squares is 90 --> a^2 + b^2 = 90Equations:
a + b = 6 -- equation 1a^2 + b^2 = 90 -- equation 2Solve (equation 1) for b in terms of a
b = a - 6 -- equation 3
(equation 3) into (equation 2)
a^2 + (a - 6)^2 = 90
a^2 + a^2 - 12a + 36 = 90
2a^2 - 12a - 54 = 0
(2a + 6)(a - 9) = 0
a = -3 -- equation 4
a = 9 -- equation 5
(equation 4) into (equation 1)
-3 + b = 6
b = 9 - --- a = -3, b= 9
(equation 5) into ( equation 1)
9 + b = 6
b = -3 - --- a = 9, b= -3
Since the numbers are interchangeable, the two numbers are -3 and 9.

what similarity statement can you write relating the three triangle in the diagram?
Answer:
D.
Step-by-step explanation:
In triangle EAK, A is the right angle.
In triangle AGK, G is the right angle.
In triangle EGA, G is the right angle.
That means we know that those letters have to be in the same position in the names of the three triangle.
The triangles are being written in the order: EAK, AGK, EGA
_A_ ~ _G_ ~ _G_
Angle E of triangle EAK corresponds to angle E of triangle EGA.
EA_ ~ _G_ ~ EG_
Angle K of triangle EAK corresponds to angle K of triangle AGK.
EAK ~ _GK ~ EG_
There is only one vertex missing in the last two triangles, so they must be A and A.
EAK ~ AGK ~ EGA

Find the value of x in the figure.
Answers:
A:7.615
B:7.154
C:9.284
D:2.67
Answer:
D: 2.67
Step-by-step explanation:
Assuming that both vertical lines are parallel, there are rules regarding angle sizes.
The rule that is specific to this question is alternate angles, this is when two angles are of the same size when they are on opposite sides of the line. This means that both equations equal each other:
10x + 13 = -3 + 16x
Add 3 to both sides to remove the negative 3 and isolate the 16x:
10x + 13 + 3 = 16x
10x + 16 = 16x
Subtract 10x from both sides of the equation to simplify:
10x + 16 - 10x = 16x - 10x
16 = 6x
Divide both sides by 6 to simplify:
6x = 16
[tex]x = \frac{16}{6}\\x = \frac{8}{3}[/tex]
Or in decimal form,
[tex]2.\overline{6} \\= 2.67[/tex]

7. Evaluate the expression ab for a = 8 and b=5.
Answer:
40
Step-by-step explanation:
First, we must know that ab is the same as:
a × b
Now, since a is given as 8, we can substitute a with 8. This is shown below:
ab = 8 × b
Similarly, b is given as 5. So, we can substitute b with 5:
ab = 8 × 5
With this, we can now evaluate ab as shown below:
ab = 8 × 5
= 40

Find the value of x.

Find the value of x so that f || g
(Image)
Answer:
x = 13 , x = 9
Step-by-step explanation:
for the lines to be parallel then 9x + 2 and 119 are alternate angles and are congruent , so
9x + 2 = 119 ( subtract 2 from both sides )
9x = 117 ( divide both sides by 9 )
x = 13
-------------------------------------------------------
For f and g to be parallel then 18x - 44 and 8x - 10 are same- side interior angles and sum to 180° , then
18x - 44 + 8x - 10 = 180 , that is
26x - 54 = 180 ( add 54 to both sides )
26x = 234 ( divide both sides by 26 )
x = 9

In three days Alexandra sold a total of 31 tickets to her school play. On Tuesday she sold as twice as many tickets as on Wednesday. And on Thursday, she sold exactly seven tickets. How many tickets did Alexandra sell on each day Tuesday through Thursday?
Answer:
Alexander sold
8 tickets on Tuesday
16 tickets on Wednesday
7 tickets on Thursday
Step-by-step explanation:
Let us represent:
Number of tickets sold on Tuesday = a
Number of tickets sold on Wednesday = b
Number of tickets sold on Thursday = c
In three days Alexandra sold a total of 31 tickets to her school play.
a + b + c = 31...... Equation 1
On Tuesday she sold as twice as many tickets as on Wednesday.
2a = b
And on Thursday, she sold exactly seven tickets.
c = 7
Substitute 2a for b and 7 for c in Equation 1
a + b + c = 31...... Equation 1
a + 2a + 7 = 31
3a = 31 - 7
3a = 24
a = 24/3
a = 8 tickets
Note that
2a = b
a = 8 tickets
2 × 8 = 16 tickets
b = 16 tickets
Therefore, Alexander sold
8 tickets on Tuesday
16 tickets on Wednesday
7 tickets on Thursday
