Find the value of x

Mathematics
1 answer:
iVinArrow [24]3 years ago
4 0

Answer:

x = 121

Step-by-step explanation:

Let the measure of the altitude of the given triangle be h units.

By geometric mean theorem:

h =  \sqrt{23 \times x}  \\  \\ h =  \sqrt{23x}  \\  \\ now \: by \: pythagors \: theorem \\  \\  {(x + 11)}^{2}  =  {h}^{2}  +  {x}^{2}  \\  \\   \cancel{{x}^{2}}  + 22x + 121 =  {( \sqrt{23x} )}^{2}  +  \cancel{{x}^{2}} \\  \\ 22x + 121 = 23x \\  \\ 22x - 23x =  - 121 \\  \\  - x =  - 121 \\  \\ x = 121

Which products result in a difference of squares or a perfect square trinomial? Check all that apply.
tiny-mole [99]

Answer:

Option B) (7x+4)(7x+4) is correct

The product result in a perfect square trinomial is

(7x+4)(7x+4)=49x^2+56x+14

Step-by-step explanation:

(7x+4)(7x+4)=(7x+4)^2 ( using (a+b)(a+b)=(a+b)^2 )

=(7x)^2+2(7x)(4)+4^2 ( using (a+b)^2=a^2+2ab+b^2 )

=7^2x^2+56x+16

=49x^2+56x+14

Therefore (7x+4)(7x+4)=49x^2+56x+14

which is a perfect square trinomial

A trinomial is a perfect square trinomial if it can be factored into a binomial multiplied to itself. In a perfect square trinomial, two terms will be perfect squares.

Option B) (7x+4)(7x+4) is correct

The product result in a perfect square trinomial is

(7x+4)(7x+4)=49x^2+56x+14

Mr. Brown is splitting his students into groups to give presentations about novels they read. He wants each group to have 4 stud
Andrei [34K]

Mr. Brown can make fewer than 6 full groups to give presentations.

<h3>Inequality</h3>

Inequality is an expression used to show the non equal comparison of two or more numbers and variables.

Let x represent how many full groups Mr. Brown can make.

He wants each group to have 4 students. There are fewer than 24 students in class today, hence:

  • 4x < 24
  • x < 6

Mr. Brown can make fewer than 6 full groups to give presentations.

Franco is adjusting a satellite because he finds it is not focusing the incoming radio waves perfectly. The shape of his satelli
xenn [34]
We have to find the focus of the parabola with equation:

y^{2}+6y-3x+3=0

In order to find the focus, we first need to convert the equation of parabola to its standard form, as shown below:

y^{2} + 6y = 3x-3 \\  \\ &#10;y^{2} + 2(y)(3) = 3x-3 \\  \\ &#10;y^{2} + 2(y)(3) + (3)^{2} = 3x-3 + (3)^{2}  \\  \\ &#10;(y + 3)^{2} = 3x + 6 \\  \\ &#10;(y+3)^{2} = 3(x+2) \\  \\ &#10;(y+3)^{2} = 4 *  \frac{3}{4} (x+2)

Comparing this equation to the similar general equation of parabola, we get:

(y-k)^{2} = 4p(x-h)

k = -3
p= 3/4
h = - 2

The focus of the general parabola is located at ( h+p, k)

Using the values, we get:

Focus of the given parabolic satellite = (-2+ \frac{3}{4},-3)=(- \frac{5}{4},-3)
