Answer:

x = 5

Step-by-step explanation:

Two secants have equal ratios when (in this case) they are split up as

AB * AC = AD*AE

Givens

AB = x-2

AC = (x - 2 + x+ 4) = 2x + 2

AD = 4

AE = 5 + 4 = 9

Substitute and solution

(x - 2) (2x + 2) = 4 (9)                  Expand the left, Combine the right

2(x^2 - x - 2) = 36                       Divide both sides by 2

x^2 - x - 2 = 18                            Subtract 18 from both sides

x^2 - x - 2 - 18 = 18 - 18              Combine

x^2 - x - 20 = 0                           This factors

(x - 5)(x + 4) = 0                           Only one of these factors works

x - 5 = 0                                       Add 5 to both sides.

x = 5

9b² - _______ + 36 =

( 3b )² - _______ + 6² =

( 3b )² - 2( 3b )( 6 ) + 6² =

( 3b )² - 36b + 6² = ( 3b - 6 )²

Answer:

Area of the rectangle = 4x^2+8x = 4x(x+2)

So if the length is (x+2), the width of the rectangle = 4x(x+2)/ (x+2) = 4x.

The length is > the width, so

x+2 > 4x, or

2 > 3x, or

(2/3) > x or

x < (2/3).

Say x = 5/9 which is < 2/3, the length = 2 + 5/9 or 23/9 and the width =20/9, which is logical.

step by step explanation

The Trinomial [tex]\rm 2x^{2} +13x+6[/tex] has a linear factor [tex]\rm (x+6)[/tex] and the other linear factor is [tex]\rm (2x+1)[/tex].

The Trinomial [tex]\rm 2x^{2} +13x+6[/tex] has a linear factor [tex]\rm (x+6)[/tex]. we need to find another linear factor say X.

[tex]\rm 2x^{2} +13x+6 = \rm (x+6)(X)[/tex]

The linear factor of the polynomial is the first-degree polynomial equations represented as [tex]\rm ax+b[/tex] and cannot be factored further.

So, the other factor X can be calculated as,

[tex]\rm 2x^{2} +13x+6 = \rm (x+6)(X)\\\rm 2x^{2} +13x+6\div \rm (x+6)=X\\\rm (x+6)\times \rm (2x+1)\div \rm (x+6)=X\\X=\rm (2x+1)[/tex]

Therefore, The Trinomial [tex]\rm 2x^{2} +13x+6[/tex] has a linear factor [tex]\rm (x+6)[/tex] and the other linear factor is [tex]\rm (2x+1)[/tex].

Step-by-step explanation:

Answer: Will need 7 week of time to afford a car worth 1932

Step-by-step explanation:

Missing information : car is worth 1932

Will works 7 hours day, 6 days a week.

=> Number of hours worked in a week = 7 * 6 = 42 hrs

paid 9.20 an hour

=> will  Weekly payment = 42 *9.2  =  386.4

will : mum = 5:2.

=> Will share = (5/7) * 386.4 =  276

car is worth  1932

Number of Weeks taken by will  to afford  a car  = 1932/276 = 7

divide 40 into ratio of 5:2

The ratio of monthly income to the saving of a family is 5:2.

Answer:

14x - 14y + 7 - x + z + 2x

There are three like terms in this expression, I made them bold for you.

Like terms are terms that have the same variable and power.

Answer:

Rewrite the function as an equation.y=−x/ 3+ 8

y=-x3+8

Rewrite in slope-intercept form. y = −1/3x+8. Use the slope-intercept form to find the slopeand y-intercept. Slope: −1/3 intercept: (0,8)(0,8) Find the values of mm and bb using the form y=mx+b

Any line can be graphed using two points. Select two xx values, and plug them into the equation to find the corresponding yy values. Graph the line using the slope and the y-intercept, or the points.Slope: −1/3

y-intercept: (0,8)

Answer: B

Step-by-step explanation:

6x + 9(-5x-3) = 6x + 9*(-5x) + 9*(-3) = 6x -45x - 27 = -39x - 27

Hope that helps!

I think the question should be as follow:

➙ 6x + 9 - ( 5x - 3 )

➙ 6x + 9 - 5 x + 3

➙ 6x - 5x + 9 + 3

➙ x + 12

➙ x = -12

Anyways I've also solved according to the provided question:

‎ㅤ‎ㅤ‎ㅤ➙ 6x + 9 (-5x - 3 )

‎ㅤ‎ㅤ‎ㅤ➙ 6x - 45x - 27

‎ㅤ‎ㅤ‎ㅤ➙ - 39 x - 27

Further, we can solve for x ;

‎ㅤ‎ㅤ‎ㅤ➙ - 39 x - 27 = 0

‎ㅤ‎ㅤ‎ㅤ➙ - 39 x = 0 + 27

‎ㅤ‎ㅤ‎ㅤ➙ x = - 27 / 39

The conditions for this type of test is that The tuition estimates in each group are approximately symmetric with no outliers.

These are the values in a statistical research that lies in positions that are way off from the values used in the data set.

There would be no outliers used here because all of the tuition estimates would be closely related for the schools.

Considering a proportional relationship for the situation, the correct conclusion is given as follows:

(17,3) is viable.

A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:

[tex]y = kx[/tex]

In which k is the constant of proportionality.

In this problem, since there is a proportional relationship, it has to have point (0,0), hence the viable points are (-2,7), (17,3) and (20,5), and the correct conclusion is:

(17,3) is viable.

There are x kids in the group

So, adults are 13-x people

(13-x)(12) + x(8) = 124

156 - 12x + 8x = 124

156 - 124 = 4x

4x = 32
