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

$2-x^2>0$
