9x² - 12x + 4 pls need ans.​

Mathematics
1 answer:
kolezko [41]3 years ago
4 0

Step-by-step explanation:

\tt{9 {x}^{2}  - 12x + 4}

Here, the second order of polynomial ax² + bx + c is factorized and expressed as the product of two linear factors. First, we have to find the two numbers that adds to 12 and if we multiply those numbers , we get 36 ( The two numbers should be 6 and 6 ).

⟶ \tt{9 {x}^{2}  - (6 + 6)x + 4}

⟶ \tt{9 {x}^{2}  - 6x - 6x + 4} { Distribute x through the parentheses )

⟶ \tt{ \underbrace{9 {x}^{2}  - 6x}} \:  -  \underbrace{6x + 4}

⟶ \tt{3x(3x - 2) - 2(3x - 2)}

⟶ \tt{(3x - 2)(3x - 2)}

⟶ \tt{ {(3x - 2)}^{2} }

\pink{ \boxed{ \boxed{ \tt{ Our \: final \: answer :  \boxed{ \underline{ \tt{{(3x - 2)}^{2} }}}}}}}

Hope I helped ! ♡

Have a wonderful day / night ! ツ

Find KL.<br> K<br> X-1<br> L<br> 12<br> M
Aneli [31]

Answer:

KL = 9

Step-by-step explanation:

(7 + x - 1)(x - 1) = 12²

(x + 6)(x - 1) = 144

x² -x + 6x - 6 = 144

reduce:

x² + 5x -150 = 0

(x + 15)(x - 10) = 0

x = -15, x = 10

KL = 10 - 1 = 9

Solve using elimination method
Anon25 [30]
X+y=8
2x^2-y=-5
elimination method means you link the 2 equations together to make one
these two already have y in the perfect form where you can cancel it out +y and -y so no need to perform any other action to a certain equation.. all you need to do is add them now
2x^2+x=3

A cylindrical pressure vessel has a height of 9 feet and a diameter of 6 feet. how much gas can the pressure vessel hold when fu
bezimeni [28]

Step-by-step explanation:

the volume of a cylinder is as for any other regular 3D object :

ground area ×height

the ground area of a cylinder is a circle, so it is

pi×radius² × height

the radius is always half of the diameter (of the diameter is airways twice the radius).

radius = 6/2 = 3 ft.

the volume is then

pi × 3² × 9 = pi × 9 × 9 = pi × 81 ft³

so, the answer is 81pi ft³.

What is the vertex of the graph y = x^2 + 6x - 5 ?
Dafna11 [192]
Given:  <span>y = x^2 + 6x - 5.  Then a = 1, b = 6 and c = -5.

The x-coord. of the vertex is given by x = -b / (2a), which here is x = -6 / (2*1) = -3.

Use the given formula </span><span>y = x^2 + 6x - 5 to find the value of y when x = -3:

y = (-3)^2 + 6(-3) - 5 = 9 - 18 - 5 = -14

Then the vertex is (-3, -14).</span>
