Answer:

$x=3$

Step-by-step explanation:

For a shape to be a parallelogram, the angles that are across from one another have to be equal.

We can now find x by making both equations equal to each other and solving.

$11x+1=13x-5$

Solve.

$11x+1=13x-5\\6=2x\\x=3$

$\bf (5x-4)^2=36\implies (5x-4)(5x-4)=36\impliedby using\ FOIL
\\\\\\
5^2x^2-40x+16=36\implies 25x^2-40x+16-36=0
\\\\\\
25x^2-40x-20=0\implies 5(5x^2-8x-4)=0
\\\\\\
5x^2-8x-4=0\implies (5x+2)(x-2)=0\implies 
\begin{cases}
5x+2=0\\
5x=-2\\\\
x=\cfrac{-2}{5}\\
-----\\
x-2=0\\
x=2
\end{cases}$

Which is a better deal 12.4 ounces for $4.99 or 21 ounces for $6.49?

ella [17]

Answer:

Getting 21 ounces for $6.49 is a better deal!

Step-by-step explanation:

4.99 / 12.4 = 0.402419...

6.49 / 21 = 0.30904...

0.4 is larger than 0.30 therefore 0.30 is less and a better deal.

Have an amazing day! ^-^
