Why the heck did my answer get deleted??

ANYWAYS

the answer is (2, 12)

the explanation is that you would add the x value to the y value. for example (x, y) + (2x, 3y) would equal (3x, 4y) because you add the x and  y values.

-4(5+n) = -12 need help​
user100 [1]

First, simplify out the brackets:

-20 - 4n = -12

Then, combine like terms by moving the -20 to the other side

-4n = -12 + 20

-4n = 8

Divide by -4 on both sides to isolate the n

n = 8/-4

n = -2

Peter is trying to buy fencing for the perimeter of his garden. His garden is in the shape of a rectangle with a length of 2(x+6
MAVERICK [17]

Given that, the length of the garden is 2(x+6)feet and width is 3.5x feet.

So, length : l = 2(x+6) and width = 3.5x.

To find the fence of the garden we need to find the perimeter of the rectangle.

Formula to find the perimeter is:

p = 2l + 2b

= 2*2(x+6) + 2*3.5x

= 4(x+6) + 7x By multiplication.

= 4x + 24 + 7x By distribution property.

= 11x + 24 Combining the like terms.

So, he need to buy 11x + 24 feet fencing.

Hope this helps you!
