Which quadrilaterals do not have parallel sides? rhombus trapezoid quadrilateral isosceles trapezoid

OLEGan [10]

So what is a quadrilateral something that has four sides. So as long as the sides DON't intersect they're fine but. A rhombus is parallel the sides won't cross. Trust me, this is a rush job. a trapezoid has only ONE parallel side but is it still parallel? It's the last option.

Find the equation of the line that is perpendicular to y = – 1 4 x – 8 and passes though the point (2, –4).

vivado [14]

The equation of the line is $y=\frac{1}{4}x-\frac{29}{7}$

Explanation:

The equation of the line is perpendicular to $y=-14 x-8$

The equation is of the form $y=mx+b$ where m=-14

Slope:

The slope of the perpendicular line can be determined using the formula,

$m_1 \cdot m_2=-1$

$-14 \cdot m_2=-1$

$m_2=\frac{1}{14}$

Thus, the slope of the line is $m=\frac{1}{14}$

Equation of the line:

The equation of the line can be determined using the formula,

$y-y_1=m(x-x_1)$

Substituting the slope $m=\frac{1}{14}$ and the point (2,-4), we get,

$y+4=\frac{1}{14}(x-2)$

Simplifying, we get,

$y+4=\frac{1}{14}x-\frac{1}{7}$

$y=\frac{1}{14}x-\frac{1}{7}-4$

$y=\frac{1}{4}x-\frac{29}{7}$

Thus, the equation of the line is $y=\frac{1}{4}x-\frac{29}{7}$

A square patio has a perimeter of (8x + 48) feet. What is the length of the patio?

4vir4ik [10]

Answer:

2x+12

Step-by-step explanation:

We have a square patio, then each side of the patio has the same lengt. As we know the perimeter of a square is the sum of all sides. Then to know the length of the patio we just need to divide by 4 the perimeter.

$\dfrac{(8x+48)}{4}=\dfrac{8x}{4}+\dfrac{48}{4}=2x+12$

Then each side of the square patio has a length of 2x+12
