Answer:

2x^2 + 19x + 9

Step-by-step explanation:

Using the FOIL method (ask me via comments if you don't know what it is), we expand it to 2x^2 + 18x + x + 9, then we add like terms, equal to 2x^2 + 19x + 9.

The trinomial expression for (2x + 1)(x + 9) is [tex]2x^2 + 19x + 9[/tex].

To express (2x + 1)(x + 9) as a trinomial, you need to perform the multiplication.

Distribute each term from the first parenthesis to each term in the second parenthesis:

(2x + 1)(x + 9) = 2x * x + 2x * 9 + 1 * x + 1 * 9

Now, simplify the expression:

[tex]= 2x^2 + 18x + x + 9[/tex]

Finally, combine like terms:

[tex]= 2x^2 + 19x + 9[/tex]

So, (2x + 1)(x + 9) expressed as a trinomial is [tex]2x^2 + 19x + 9.[/tex]

For x = -5 the equation [tex]-8(x+5) = -3x\;-7\;+x\;-3[/tex] is a true equation. Hence, OPTION (B) IS CORRECT.

We have the following equation -

[tex]-8(x+5) = -3x\;-7\;+x\;-3[/tex]

We have to find the value of x that makes this equation true.

In order to prove that the equation is true at x = 2 and x = 0, we have to prove that the left hand side of the equation equals the right hand side of the equation, if we substitute 2 or 0 in place of x Solving the equation to find the value of x -

[tex]x^{2} =2x\\x^{2} -2x=0\\[/tex]

x (x - 2) = 0

x = 0          or           x - 2 = 0

Test case 1 : for [tex]x = 2[/tex]

[tex]x^{2} =2x\\2^{2} =2 (2)\\4 =4[/tex]

LHS = RHS

Test case 2 : for [tex]x =0[/tex]

[tex]x^{2} =2x[/tex]

[tex]0^{2} = 2(0)[/tex]

[tex]0 = 0[/tex]

LHS = RHS

Hence, the equation [tex]x^{2} = 2x[/tex] is a true equation for [tex]x=0[/tex] and [tex]x=2[/tex]

We can use the similar approach in the equation -

                                     [tex]-8(x+5) = -3x\;-7\;+x\;-3[/tex]

to find the value of [tex]x[/tex] for which the equation is true.

-8(x+5) = -3x-7+x-3

-8x-40=-2x-10

-8x+2x = -10+40

-6x = 30

x=-5

Hence, for x = -5 the equation [tex]-8(x+5) = -3x\;-7\;+x\;-3[/tex] is true equation.

Answer:

19 and 2

Step-by-step explanation:

Let x represent the first number and y represents second number

x + y = 19

x - y = 17 add two equations up

2x = 36 divide both sides by 2

x = 19 and since the difference is 17 the other number is 2

Answer:

The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y).

Answer:

The reflection will be on the first quadrant

Step-by-step explanation:

Here, we want to reflect the given point over the y-axis

By reflecting over the y-axis, we simply have to negate the x-coordinate value

So after the reflection, the point (-8,5) becomes (8,5)

(8,5) is a point on the first quadrant

So we have the position after the reflection on the first quadrant

Step-by-step explanation:

Answer: Events A and B are independent because P (A l B )  =  P(B)

The events A and B are independent because P(A and B) = P(A)×P(B).

Two events are independent if the occurrence of one event does not affect the chances of the occurrence of the other event. The mathematical formulation of the independence of events A and B is the probability of the occurrence of both A and B being equal to the product of the probabilities of A and B (i.e., P(A and B).

The given parameters are:

P(A) = 0.2

P(B) = 0.3

P(A and B) = 0.06

Two events A and B are independent if

P(A and B) = P(A)×P(B)

Here, we have 0.06 = 0.2 * 0.3

⇒ 0.06 = 0.06

Therefore, the events A and B are independent because P(A and B) = P(A)×P(B).

Solution :

Given :

Span of the roof = 48 feet

Length of the rafter = 30 feet (including the 4 feet overhung)

So, for the 30 feet long rafter, 26 feet will be rafter length from the high point of the roof to the edge of the roof and 4 feet will be the roof overhung.

Therefore, the horizontal span per rafter is

[tex]$=\frac{48}{2}$[/tex]

= 24 feet

a). So the rise of the roof is [tex]$= \sqrt{(26)^2-(24)^2}$[/tex]  

                                         = 10 feet

b). Pinch of the roof is [tex]$=\frac{\text{rise}}{\text{run}}$[/tex]

                                     [tex]$=\frac{10}{24}$[/tex]

                                     [tex]$=\frac{5}{12}$[/tex]

c). The percent of the roof used as overhung is

     [tex]$=\frac{4+4}{60}\times 100$[/tex]

     [tex]$=\frac{80}{6}$[/tex]

       = 13.33 %
