Answer:

The new length of the garden is 80 ft, the new width is 40 ft, and the total area of the new garden is 3200 ft². The area of the new garden will be 8 times larger than the current one. Jane should make her garden 4 times the current length.

Step-by-step explanation:

Juan's garden is 40 ft in length, he wishes to make the length 2 times longer:

2 \times 40 = 80

Juan's garden is 10 ft in width, he wishes to make the width 4 times longer:

4 \times 10 = 40

With a length of 80 and width of 40, the total area of the garden is

40 \times 80 = 3200

Since Juan wanted to make the length 2 times longer and the width 4 times longer, the total area of the garden will be

2 \times 4 = 8

larger than the current garden.

Jane wants to make her garden 20 times the size. Since she's making her garden 5 times longer in width, she needs to make the length of her garden

\frac{20}{5} = 4

4 times longer.

Write a decimal subtraction problem that requires regrouping to solve. then solve the problem
Svetach [21]
For example, think about 8.4 - 2.9.

You have to regroup because you can't subract 4 - 9.
4 turns into a 14 since you borrow from the left number, 8.
8 turns into a 7 after that.
Now, you have to subtract 14 - 9 and 7 - 2. You're answer is 5.5.
You can check your work by doing inverse opperations:
By adding:
5.5 + 2.9 = 8.4
Or by subracting 8.4 - 5.5 = 2.9

Hope this helped you! If you need a better explaination or another example, I will be happy to help you! :)

Answer:

5x+2 , 2x^2+5x-2,\frac{x^2+5x}{2-x^2}

Step-by-step explanation:

We are given f(x) and g(x)

1. (f+g)(x)

(f+g)(x) = f(x) + g(x)

           = x^2+5x+2-x^2

           = 5x+2

Domain : All real numbers as it there exists a value of (f+g)(x) f every x .

2. (f-g)(x)

(f-g)(x) = f(x)-g(x)

          = x^2+5x-2+x^2

          =2x^2+5x-2

Domain : All real numbers as it there exists a value of (f-g)(x) f every x .

Part 3 .

(\frac{f}{g})(x)\\(\frac{f}{g})(x) = \frac{f(x)}{g(x)}\\=\frac{x^2+5x}{2-x^2}

Domain : In this case we see that the function is not defined for values of x for which the denominator becomes 0 or less than zero . Hence only those values of x are defined for which

2-x^2>0

or 2>x^2

   Hence taking square roots on both sides and solving inequality we get.

-\sqrt{2}

which equation and ordered pair represent the correct vertex form and vertex for j(x) = x^2 - 12 x +7?
Aliun [14]

Answer:

see explanation

Step-by-step explanation:

the equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Given the equation in standard form : ax² + bx + c : a ≠ 0

then the x-coordinate of the vertex is

x_{vertex} = - \frac{b}{2a}

j(x) = x² - 12x + 7 is in standard form

with a = 1, b = - 12 and c = 7, hence

x_{vertex} = - \frac{-12}{2} = 6

substitute x = 6 into j(x) for y- coordinate

y = 6² - 12(6) + 7 = 36 - 72 + 7 = - 29

vertex = (6, - 29 ) and

j(x) = (x - 6)² - 29 ← equation in vertex form
