A model of a rectangular patio at a landscaping business will be enlarged by a scale factor of 2 when it is installed in a custo

VARVARA [1.3K]

Answer:

C) The area of the landscape model is A = 40 sq ft.

Step-by-step explanation:

The original dimensions of the rectangular patio model is

Length = L

Width = W

Area of the patio model = LENGTH x WIDTH = L x W

⇒ A = L W ............. (1)

Now, the new area A" is enlarged by a factor of 2

⇒ The new Length = L" = (2 L)

The new Width = W" = (2 W)

So, AREA" = L" x W" = (2 L) x (2 W) = 4 (L W)

⇒ A " = 4 (L W)

But, L W = A .. from (1)

⇒ A" = 4 A

But, the area of the new enlarged patio is 160 square feet.

⇒ 160 sq ft = 4 x A

or, A = 160 / 4 =40 sq ft

⇒ A = 40 sq ft.

Hence, the area of the landscape model is A = 40 sq ft.

Which of the following equations is equivalent to -2(2 − 2x) = 4 − 8(1 − x) ?

Strike441 [17]

Answer:

0 = 4x

Step-by-step explanation:

-2(2 - 2x) = 4 - 8(1 - x)

-4 + 4x = 4 - 8 + 8x

-4 + 4x = -4 + 8x

-4 + 4 = 8x - 4x

0 = 4x

Without graphing, determine whether the following pair of lines are parallel, perpendicular, or neither parallel nor perpendicul

Tomtit [17]

Write the equation of the lines in slope-intercept form (y=mx+b)

First equation: It is already in slope-intercept form

$y=\frac{2}{5}x-4$

Second equation: solve y:

$\begin{gathered} 4x-10y=-7 \\ 4x-4x-10y=-4x-7 \\ -10y=-4x-7 \\ \frac{-10}{-10}y=\frac{-4}{-10}x-\frac{7}{-10} \\ \\ y=\frac{4}{10}x+\frac{7}{10} \\ \\ y=\frac{2}{5}x+\frac{7}{10} \end{gathered}$

Identify the slope of each line:

If two or more lines have the same slope then the lines are parallel

If two lines have slopes that are negative reciprocals then the lines are perpendicular

The two given lines have the same slope: 2/5. Then, they are parallel lines
