Answer:

  3x² -17x +10

Step-by-step explanation:

Use the distributive property and collect terms.

  (x -5)(3x -2) = x(3x -2) -5(3x -2)

  = (3x² -2x) +(-15x +10)

  = 3x² -17x +10

Using a quadratic equation according to the area of the rectangular mat, it is found that:

The area of a rectangle of length l and width w is given by:

[tex]A = lw[/tex]

In this problem:

[tex]lw = 714[/tex]

[tex](25 + 4x)(21 + 2x) = 714[/tex]

[tex]8x^2 + 134x + 525 = 714[/tex]

[tex]8x^2 + 134x - 189 = 0[/tex]

Which is a quadratic equation with [tex]a = 8, b = 134, c = -189[/tex].

The, to find the widths of the mat, we have to first find the value of x, solving the quadratic equation.

[tex]\Delta = 134^2 - 4(8)(-189) = 24004 [/tex]

[tex]x_{1} = \frac{-134 + \sqrt{24004}}{2(8)} = 0.654[/tex]

[tex]x_{2} = \frac{-134 - \sqrt{24004}}{2(8)} = -9.03[/tex]  

We are interest in the positive value of x, so x = 0.654.

[tex]2(0.654) = 1.308[/tex]

Step-by-step explanation:

The domain of function H(t) is 0 ≤ t ≤ 20.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

From the graph,

We see that the value of t is from 0 to 20 seconds.

Now,

The value of t can be written as an inequality:

0 ≤ t ≤ 20

Thus,

The domain of function H(t) is 0 ≤ t ≤ 20.

% / 100 = Part / Whole

replace the given values:

85 / 100 = Part / 620

Cross multiply:

= 85 x 620 = 100 x Part

= 52700 = 100 x Part

Now, divide by 100 and get the answer:

Part = 52700 / 100 = 527

https://brainly.com/question/24983242 help

Step-by-step explanation:

12 + 4[5% - 4(x + 5)] = 7 - 5x

12 + 4•(5% - 4•(x + 5)) = 7 - 5•x

11x = -55

x = -5

Answer:

[tex]x = - \frac{34}{5} [/tex]

Step-by-step explanation:

12 + 4 (5% - 4(x + 5)) = 7 - 5x

12 + 4 (5/100 - 4x - 20) = 7 - 5x

12 + 4 (-399/20 - 4x) = 7 - 5x

12 - 399/5 - 16x = 7 - 5x

-399/5 - 16x = 7 - 5x

-16x + 5x = 7 + 339/5

-11x = 374/5

x = -34/5
