Rico thinks it's a perfect square triinomiall. Teresa says it's the difference of two squares. Who is
correct. -9x2-30x-25

Answers

Answer: Rico is right.

(-1)(3x + 5)²

Step-by-step explanation: If it were the difference of two squares, the -30x would not be there.

It makes sense to factor out (-1) fry the trinomial, leaving all positive terms.

Then factor 9x² + 30x + 25 as

(3x + 5)²

Ok so the answer is sqrt of 39 but think about

Step-by-step explanation:

sqrt81 is 9 which is a whole number it is rational

sqrt16 is 4 which again is a whole number and is rational

1.9 is rational because it can be written as a fraction or ratio

but sqrt39 is a repeating decimal that goes on forever it still is a real number not fitting into the imaginary category but not a ration number.

Expand and simplify ([tex]2x^{2}[/tex]+3)(4x+5)-8x([tex]x^{2}[/tex]-2)

Answers

Answer:

2x(5x + 14) + 15

Step-by-step explanation:

Given: (2[tex]x^{2}[/tex] + 3)(4x + 5) - 8x([tex]x^{2}[/tex] - 2)

(2[tex]x^{2}[/tex] + 3)(4x + 5) - 8x([tex]x^{2}[/tex] - 2) = 2[tex]x^{2}[/tex](4x + 5) + 3(4x + 5) - 8x([tex]x^{2}[/tex] - 2)

                              = (8[tex]x^{3}[/tex] + 10[tex]x^{2}[/tex] + 12x + 15) - 8[tex]x^{3}[/tex] + 16x

                              = 8[tex]x^{3}[/tex] + 10[tex]x^{2}[/tex] + 12x + 15 - 8[tex]x^{3}[/tex] + 16x

collecting like terms to have,

8[tex]x^{3}[/tex]- 8[tex]x^{3}[/tex] + 10[tex]x^{2}[/tex] + 12x + 16x + 15

10[tex]x^{2}[/tex] + 28x + 15

Thus,

(2[tex]x^{2}[/tex] + 3)(4x + 5) - 8x([tex]x^{2}[/tex] - 2) = 10[tex]x^{2}[/tex] + 28x + 15

                                           = 2x(5x + 14) + 15

Step-by-step explanation:

Point S lies between points R and T on Line segment R T. A line contains points R, S, T. The space between R and S is 2 x. The space between S and T is 3 x. If RT is 10 centimeters long, what is ST? 2 centimeters 4 centimeters 6 centimeters 8 centimeters

Answers

Answer:

6 cm

Step-by-step explanation:

Given that:

A line that contains the points R, S and T.

Distance between R and S = [tex]2x[/tex]

Distance between S and T = [tex]3x[/tex]

To find:

The distance between S and T = ?

Solution:

The given situation and dimensions can be represented in the form of a diagram as shown in the attached diagram.

As per given statement and in the diagram, we can deduce that the sum of distance between R and S, S and T is equal to distance between R and T.

i.e. RS + ST = RT

[tex]2x + 3x = 10\\\Rightarrow 5x=10\\\Rightarrow x = 2[/tex]

ST = 3[tex]x[/tex] = 3 [tex]\times[/tex] 2 = 6 cm

Therefore, the answer is:

Distance between S and T is 6 cm.

If the space between R and S is 2x, the space between S and T is 3x, and RT is 10 centimeters long, then ST is 6 centimeters

Point S lies between points R and T on Line segment RT

RT   =  RS   +  ST

The space between R and S is 2x

That is, RS  =  2x

The space between S and T is 3x

That is, ST  =  3x

RT is 10 centimeters long

RT  =  10cm

Substitute RT = 10, ST = 3x and RS = 2x into the equation RT = RS + ST

10  =  2x  +  3x

10   =  5x

x  =  10/5

x   =  2

If x = 2, then

ST  =  3x

ST = 3(2)

ST =  6 centimeters

Answers

Answer:

The missing value is 6!

Step-by-Step Explanation:

First, we know that there are 4 values in total, so we must multiply the mean, 7, by 4 to get the total sum of all the values. (7*4=28)

Now, we can write this as a function, where we can represent the missing value as 'x'.

[tex]4+5+13+x=28[/tex]

In order to get the missing value, we must solve the equation.

Step 1: Simplify.

[tex]4+5+13+x=28\\22+x=28[/tex]

Step 2: Subtract 22 from both sides.

[tex]22+x=28\\22+x-22=28-22\\x=6[/tex]

x is equal to 6, which means the missing volume of gas is 6!

Teresa is going with her family to watch

buys 6 tickets. They have a coupon for

$1.50 off each ticket. They pay $52.50

altogether for their tickets. Write an

equation that you could use to represent

the situation. What is the price of a ticket

before using the coupon?

Answers

Answer:

6 * (x - 1.50) = 52.50 ; 10.25

Step-by-step explanation:

Given that :

Number of tickets purchased = 6

Coupon off per ticket = 1.50

Total Amount paid for tickets = $52.50

Let x = initial price of ticket :

Number of tickets purchased * (Initial ticket price - coupon) = total amount paid

6 * (x - 1.50) = 52.50

6x - 9 = 52.50

6x = 52.50 + 9

6x = 61.50

x = 61.50 / 6

x = 10.25

Hence, initial price of ticket = $10.25
