OK, so I was learning about how to factorize a quadratic polynomial. And I also wrote notes on it. Now, even though I know that my notes are definitely correct, I’m getting stuck at a certain point. Please look at the attached photo, and explain why the variable X and the number 4 have been removed when we get the factors. I’d greatly appreciate it. Thanks!
Answer:
so when factorising, you first remove the common factors. in this case it is (x+3)
so what is remaining is the x and 4
you group that together.
my teacher explained that when factorising, after removing the common factor then you divide each term by the common factor, and then group the answers to that in brackets.
so it will be,
[tex]x(x + 3) + 4(x + 3) \\ (x + 3)( \frac{x(x + 3)}{x + 3} + \frac{4(x + 3)}{(x + 3)} [/tex]
so basically whats left after dividing, is x and 4 because the x+3 cancel off.
and thats how you get the answer of
(x+3)(x+4)
hope this helps;)

Rena has 30 tickets for the baseball game. She gives 8 tickets to Tariq and 10 tickets to Marita. Which set of equations could be used to represent how many tickets Rena should have left after she gives away the tickets to Tariq and Marita?
A. 8 + 10 = 18
30 - 18 = y
B. 30 + 8 = 38
38 - y = 18
C. 30 - 10 = 20
20 + 8 = y
D. 30 - 12 = 18
18 - y = 10
Ana María tiene $ 30.000 en su cuenta vista y retira $ 18.000 para un pago. Luego el Banco paga un cheque de $ 26.000 con cargo a la cuenta de Ana María y finalmente le descuentan una comisión por mantenimiento de la cuenta equivalente a $ 2.500. ¿Cuál es el saldo de su cuenta?
Answer:
El saldo de la cuenta de Ana María es de -$16.500 , es decir, Ana María debe al banco $16.500.
Step-by-step explanation:
Ana María tiene $ 30.000 en su cuenta vista y retira $ 18.000 para un pago. Para saber la cantidad de dinero que posee en su cuenta luego de retirar el dinero debes realizar la diferencia (resta) entre lo que tiene inicialmente y la cantidad que retira:
$30.000 - $18.000= $12.000
Ahora el Banco paga un cheque de $ 26.000 con cargo a la cuenta de Ana María, por lo que debe restarse la mencionada cantidad a la suma de dinero que Ana María posee luego del retiro de dinero [un cheque con cargo a la cuenta de una persona indica que para el titular de la misma significa una salida de fondos, y por tanto, una disminución de su saldo]:
$12.000 - $26.000= - $14.000
Finalmente le descuentan una comisión por mantenimiento de la cuenta equivalente a $ 2.500, por lo que se debe realizar la diferencia entre la cantidad calculada previamente y $2.500:
- $14.000 - $2.500= -$16.500
El saldo de la cuenta de Ana María es de -$16.500 , es decir, Ana María debe al banco $16.500.

A ball is thrown from an initial height of 4 feet with an initial upward velocity of 30 feet per second.
Answer:
I guess that we want to find the position equation for the ball.
First, we know that any object that is in the air has acceleration equal to the gravitational acceleration (where we ignore forces like air resistance and others) so we can write the acceleration equation as:
a(t) = -32 ft/s^2
Where 32 ft/s^2 is the gravitational acceleration, and the negative sign is because this acceleration is downwards.
To get the velocity equation, we can integrate over time to get:
v(t) = (-32 ft/s^2)*t + v0
where v0 is the initial velocity.
We know that the ball is thrown upwards with a velocity of 30 ft/s, then:
v0 = 30ft/s
And the velocity equation becomes:
v(t) = (-32 ft/s^2)*t + 30 ft/s
Finally, for the position equation we need to integrate again, to get:
p(t) = (1/2)*(-32 ft/s^2)*t^2 + (30 ft/s)*t + p0
where p0 is the initial position.
We know that the ball is thrown from an initial height of 4 ft, then:
p0 = 4ft
Then the position equation (or height equation) of the ball is:
p(t) = (1/2)*(-32 ft/s^2)*t^2 + (30 ft/s)*t + 4 ft

11. Kevin is comparing job offers at two stores.
Dollar Deal offers $8/h plus 10% commission.
Great Discounts offers $18/h with no
commission. What do Kevin's weekly sales
need to be in order for Dollar Deal to pay
more? Assume that he works an 8-h day five
days per week.
Answer:
Kevin's weekly sales will have to be worth more than $4000 in order for Dollar Deal to pay more.
Step-by-step explanation:
Dollar Deal offers $8/h plus 10% commission.
If he spends x hours, then offer after x hours and s amount from sales is;
8x + 10%s
This can be rewritten as; 8x + 0.1s
Now, Great Discounts offers $18/h with no commission.
Thus after 8 hours for 5 days, total number of hours = 40 hours.
Thus, great discounts offer = 18 × 40 = $720
Now, dollar deal will offer; 8(40) + 0.1s = 320 + 0.1s
Thus, for dollar deal to pay more weekly, then;
320 + 0.1s > 720
0.1s > 720 - 320
0.1s > 400
s > 400/0.1
s > 4000

What is the measure of EGF?
What is the measure of CGF?
Answer:
65 degree, 15 degree
Step-by-step explanation:
In triangle GEF,
∠E = ∠G (Given)
Let's say,
∠E = ∠G = x
∠E + ∠G + ∠F = 180 (Angle sum property of Triangle)
=>x + x + ∠F = 180
=>2x + ∠F = 180
=>2x + 50 = 180
=>2x = 180-50
=> 2x =130
=> x = 130/2
=> x = 65
=>∠E = ∠G = 65
=>∠GEF = ∠EGF = 65 Degree
∠EGF + ∠CGF = 180
=>65 + ∠CGF =180
=>∠CGF = 180 - 65
=> ∠CGF = 15

An electric blender has a price of $240 after import duty is added to the cost price.What is the cost price of the blender if import duty is 20%?
Answer:
$200
Step-by-step explanation:
Given :
Cost of blender + import duty = $240
Import duty = 20% of cost price
Let :
Cost of blender = x
Import duty = 20% of x = 0.2x
Therefore,
x + 0.2x = $240
1.2x = 240
x = 240 / 1.2
x = $200
Cost of blender = $200

Consider the graph of the function f(x) =
= 10^x
What is the y-intercept of function gif g(x)
=4f(x) + 12
Answer:
(0,8)
Step-by-step explanation:
Let X be 0 and solve for Y to get the intercept
y= - 4([tex]10^{x}[/tex]) + 12
y= - 4 * [tex]10x^{0}[/tex] + 12
y= - 4 * 1 + 12
y= - 4 + 12
y=8
when x=0, y=8
(0,8) is y intercept
The y-intercept of the given function is (0,8).
We have given that,
The graph of the function f(x) = 10^x
The y-intercept of function gif g(x)=4f(x) + 12
What is the intercept?
The x-intercept is the point where a line crosses the x-axis, and the y-intercept is the point where a line crosses the y-axis.
Let X be 0 and solve for Y to get the intercept
[tex]y= - 4(10^x) + 12[/tex]
[tex]y= - 4 (10^0) + 12[/tex]
[tex]y= - 4 * 1 + 12[/tex]
[tex]y= - 4 + 12[/tex]
[tex]y=8[/tex]
when x=0, y=8
The y-intercept of the given function is (0,8).

w=-7/2 z
w=-2/7 z
w=-2z
w= -7z
Answer:
w = - [tex]\frac{7}{2}[/tex] z
Step-by-step explanation:
Given
5w + 9z = 2z + 3w ( subtract 3w from both sides )
2w + 9z = 2z ( subtract 9z from both sides )
2w = - 7z ( divide both sides by 2 )
w = - [tex]\frac{7}{2}[/tex] z

Answer:
x = 152°
Step-by-step explanation:
∠ BDE = ∠ ABD = 76° ( alternate angles )
Since DE = BE then Δ BDE is isosceles with base angles congruent
∠ DBE = ∠ BDE = 76°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
x is an exterior angle of the triangle, then
x = 76° + 76° = 152°
