Answer:

73.72 ft Squared

Step-by-step explanation:

First you need to find the area of the rectangle the area of rectangle is 8x10=80. Then You take that 80=3.14x2. then you find the area by dividing it. so...

1.) 80=3.14x2

3.14x2=6.28 80=6.28 (Then you divide 6.28 by 80)

80 80

Three times the square of the difference of x and 6 is 12

Elis [28]

Answer:

Equation: $3(x-6)^2=12$

Solutions: $x=4\text{ or }x=8$

Step-by-step explanation:

Unknown variable $= x$

Difference of x and 6 $= x - 6$

Square of the difference of x and 6 $=(x-6)^2$

Three times the square of the difference of x and 6 $=3(x-6)^2$

Three times the square of the difference of x and 6 is 12, then

$3(x-6)^2=12$

Divide this equation by 3:

$(x-6)^2 =4$

Now

$x-6=2\text{ or }x-6=-2\\ \\x=2+6\text{ or }x=-2+6\\ \\x=8\text{ or }x=4$

Choose the correct way to end the sentence.

Answer: B) neither

================================================

Let's isolate y in the first equation. This way we can find the slope.

x-2y = 4

-2y = 4-x

-2y = -x+4

y = (-x+4)/(-2)

y = -x/(-2) + 4/(-2)

y = (1/2)x - 2

This matches with y = mx+b form with m = 1/2 being the slope.

The slope of y = 2x-2 is m = 2

------------------------------

The slope of the first line is 1/2 and the slope of the second line is 2.

Since the two slopes (1/2 and 2) are not equal, this means the lines are not parallel.

Also, the two slopes do not multiply to -1, so the lines aren't perpendicular either.

This leads to B) neither as the final answer.
