[tex](8x-17)(5x+19)\\40x^{2}+152x-85x-323\\ 40x^{2}+67x-323[/tex]

Answer:

For [tex]x \in\mathbb{C}[/tex]

[tex]x = -2i[/tex]

[tex]x = 2i[/tex]

[tex]x = 7[/tex]

Step-by-step explanation:

[tex]f(x)=x^3-7x^2+4x-28[/tex]

For [tex]f(x) = 0[/tex]

[tex]x^3-7x^2+4x-28 = 0[/tex]

We can easily factor the expression [tex]x^3-7x^2+4x-28[/tex] by grouping.

[tex]x^3-7x^2+4x-28 = (x^3-7x^2)+(4x-28) = x^2(x-7)+4(x-7) = \boxed{(x^2+4)(x-7) }[/tex]

Now we have

[tex](x^2+4)(x-7) = 0[/tex]

Therefore,

[tex]x^2+4 = 0 \text{ or } x-7 = 0[/tex]

So,

[tex]x^2 = -4 \implies x = \pm\sqrt{-4}[/tex]

Once [tex]\sqrt{-1} = i[/tex]

[tex]x = \pm\sqrt{-4} = \pm\sqrt{4}\sqrt{-1} = \pm 2i[/tex]

order the numbers from least to greatest and then subtract the lowest number from the greatest

ex : 4,6,9,3,7

the lowest number is 3 and the highest is 9 so 9-3 = 6 so for this example the answer is 6.

Answer:

Step-by-step explanation:

To get maximum product we need to optimize how we break down the numbers

Its obvious we don't want number 1 to be used as it won't change the product

Also we don't want to use big numbers, we can have four 5's instead of two 10's as it would give greater product, 5*5 > 10

What is best number?

So the best is to break the number down to 2's and 3's

As we see the maximum product we can get is 4374 with seven 3's and one 2.

Hence the numbers are:

Answer:

your answer should be     3, 3, 3, 3, 3, 3, 3, 2

= 4^1/2 /4^1/3

=4^1/2-1/3

=4^1/6

9514 1404 393

Answer:

Step-by-step explanation:

The perimeter is twice the sum of length and width. Then the sum of length and width is 90 yards. Their product is the area, so we have ...

  x(90 -x) = 2000 . . . . where x is length or width

  x^2 -90x +2000 = 0 . . . . rearrange to standard form

  (x -40)(x -50) = 0 . . . . . . . factor

  x = 40  or  x = 50

The dimensions of the rectangular plot are 40 yards by 50 yards.

Step-by-step explanation:

Answer:

[tex]y = 16\frac{2}{3} x + 100[/tex] or [tex]y = \frac{50}{3} + 100[/tex]

Step-by-step explanation:

The equation of a line is [tex]y = mx + b[/tex], with [tex]m[/tex] being the slope and [tex]b[/tex] being the y-intercept.

We can see on the graph that the y-intercept, where the line crosses or touches the y-axis, is 100. So, our new equation is [tex]y = mx + 100[/tex].

Now we have to find the slope. Let's pick a point that's clearly on the graph. Perhaps (3, 150). And then we'll take the y-intercept point for convenience, (0, 100).

Then, we'll use [tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1} }[/tex] to find the slope.

Let's substitute in our points.

[tex]\frac{150-100}{3-0}[/tex]

Simplify.

[tex]\frac{50}{3}[/tex]

Now, we can leave the slope like that or turn it into a mixed number. As a mixed number, your slope is [tex]16\frac{2}{3}[/tex].

We'll put that in our equation for a line and...bam!

[tex]y = 16\frac{2}{3} x + 100[/tex] or [tex]y = \frac{50}{3} + 100[/tex]

Answer:

Selling the total for $ 1276, Ace lost $ 1.37 for each meter.

Step-by-step explanation:

Given that Ace earned $ 176 selling 32 meters of cloth at $ 1496, to find out his loss for each meter if he sold the total for $ 1276, the following calculation must be performed:

1496 - 176 = 1320 (stock price)

1320/32 = 41.25 (price per meter)

1276/32 = 39.87

41.25 - 39.87 = 1.37

Thus, selling the total for $ 1276, Ace lost $ 1.37 for each meter.

Answer:

$2750/month

Step-by-step explanation:

Answer:

Step-by-step explanation:

A.)

[tex]a^{2} + b^{2} = c^{2}[/tex]

[tex]16^{2} +20^{2}= c^{2}[/tex]

256 + 400 = [tex]c^{2}[/tex]

656 = [tex]c^{2}[/tex]

25.6 = c

__________________________________________________________

B.)

[tex]a^{2} + b^{2} = c^{2}[/tex]

[tex]25^{2}+ 10^{2} = c^{2}[/tex]

625 + 100 = [tex]c^{2}[/tex]

725 = [tex]c^{2}[/tex]

26.9 = c

__________________________________________________________

C.)

[tex]a^{2} + b^{2} = c^{2}[/tex]

[tex]12^{2} +10^{2}= c^{2}[/tex]

144 + 100 = [tex]c^{2}[/tex]

244 = [tex]c^{2}[/tex]

15.6 = c

__________________________________________________________

D.)

[tex]a^{2} + b^{2} = c^{2}[/tex]

[tex]26^{2}+ 24^{2} =c^{2}[/tex]

676 + 576 =  [tex]c^{2}[/tex]

1,252 =  [tex]c^{2}[/tex]

35.4

Sum of angles in a triangle is 180 degrees

180-40-60 = 80

80 degrees

80 degrees is an acute angle.

Answer:

It would be 80 degrees which is an acute angle
