Your neighbor has decided to enlarge his garden. The garden is rectangular with width 6 feet and length 15 feet. The new garden

Nana76 [90]

Answer:

Original garden: 42 feet

Enlarged garden: 98 feet

Step-by-step explanation:

Perimeter = length (2) + width (2)

Original perimeter:

P = 15(2) + 6(2)

P = 30 + 12

P = 42 feet

In this problem, similar is proportional, so the new garden will be proportional to the old one.

If the original length was 15 and the new length is 35, then 15 would have had to have been multiplied by 2 1/3. That means you need to multiply 6 by 2 1/3, which is 14. That means the dimensions of the enlarged yard is 14 (width) × 35 (length).

Enlarged perimeter

P = 35(2) + 14(2)

P = 70 + 28

P = 98 feet

Question #2 What is the difference?

e-lub [12.9K]

Answer:

B $\frac{b-10}{b-1}$

Step-by-step explanation:

In order to get the same denominator, we need to multiply the second fraction by (b+2) in the numerator and denominator.

We will end up in something like this : $\frac{b^{2} - 2b - 8 -6(b+2) }{(b-1)(b+2)}$

I just timed the second fraction by b+ 2 and then i added them together.

Therefore, we will get $\frac{b^{2} - 8b - 20}{(b-1)(b-2)}$

now factoring the numerator we will end like this

$\frac{(b-10)(b+2)}{(b-1)(b+2)}$

we will then end up with the answer.

Hope this helps.
