12. brick is a square
4x -4
?
A
paver
with
sides of x feet in length. A
gardener is using the pavers for
the border of the custom
garden shown. The perimeter 3x
of the garden is 100 feet.
What is the length of the 4th side?
7x + 3

the answer is a i belaeve atleast thats what my calculator just gfave me

step-by-step explanation:

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

he can fill 250 bottles completely

step-by-step explanation:

so part 1: the y values stay the same, but the x values are opposite signs.

part 2 & 3: the line will be of equal lengths and will be straight.

part 4: you'd see the same characteristic because the x coordinate becomes a negative making them at equal distances from the y axis?
