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

$\\ \rm\rightarrowtail x(x+7)-3(x+7)$

$\\ \rm\rightarrowtail (x-3)(x+7)$

Solve -2x+3y=-9 4x-6y=2

mr Goodwill [35]

Step-by-step explanation:

Given,

-2x + 3y = -9 ------- (eqⁿ 1)

4x - 6y = 2 ----------- (eqⁿ 2 )

now,

multiply eqⁿ 1 by 2

so we got,

-4x + 6y = -18 -------- (eqⁿ 3)

now,

subtract eqⁿ 2 from eqⁿ 3

we got,

-8x = -16

x = -16/-8

x = 2,

so , after putting values in the eqⁿ 2

we got,

4(2) - 6y = 2

8 - 6y = 2

6y = 2 - 8 = 6

y = 6/6

y = 1

x = 2 and y = 1

hope this answer helps you dear...take care!
