guajiro [1.7K]

Answer:

$4+5\left(6p+2\right)=24$

$4+5\left(6p+2\right)-4=24-4$

$5\left(6p+2\right)=20$

$\frac{5\left(6p+2\right)}{5}=\frac{20}{5}$

$6p+2=4$

$6p+2-2=4-2$

$6p=2$

$p=\frac{1}{3}$

Perimeter of rectangle is 48 inches area is 40 inches what are the length of the side

Aloiza [94]

$\bf \textit{perimeter of a rectangle}=p=side+side+side+side
\\\\
or\implies p=w+w+l+l\implies p=2w+2l
\\\\
p=2(w+l)\qquad 
\begin{cases}
w=width\\
l=length\\
------\\
p=48
\end{cases}\implies 40=2(w+l)\\\\
-----------------------------\\\\
\textit{area of it}=A=w\cdot l\qquad \begin{cases}
w=width\\
l=length\\
------\\
A=40
\end{cases}\implies 40=wl\\\\
-----------------------------\\\\$

$\bf thus\qquad 
\begin{cases}
40=2(w+l)\to \frac{40}{2}=w+l\to\frac{40}{2}-l=\boxed{w}
\\\\
40=wl\\
--------------\\
40=\left( \boxed{\frac{40}{2}-l} \right)\cdot l
\end{cases}$

solve for "l" to find its length

Which is not a true statement about the transformation shown below?

IrinaVladis [17]

Answer: C: The orientation of the figure stayed the same

Step-by-step explanation:

Everything else is true

A. The figures do not change in dilation so they are still congruent

B. The pre-image does start in the top left which is quadrant 1

C. The orientation changes because the picture is reflected instead of translated so points D and E are in different respective locations

D. The image is a reflection. You can tell because both points D and E reflect across the Y-axis
