X=7. The two segments on the bottom as well as on the diagonal are the same length. This shows that the entire triangle and the inner triangle on the right are similar. So if we call the length of the bottom 2y, then 84/2y=6x/y. Solving this we get 84=12x, and so x=7

The perimeter of a parallelogram must be no less than 40 feet. The length of the rectangle is 6 feet. What are the possible meas

tatuchka [14]

Answer: $14\ ft$

Step-by-step explanation:

Given

Length of rectangle is $6\ ft$

Perimeter must be greater than 40 ft

Suppose l and w be the length and width of the rectangle

$\Rightarrow \text{Perimeter P=}2(l+w)\\\Rightarrow P\geq 40\\\Rightarrow 2(l+w)\geq40\\\Rightarrow l+w\geq20\\\Rightarrow w\geq20-6\\\Rightarrow w\geq14\ ft$

So, the smallest width can be $14\ ft$

What is bigger 400 pints or 100 gallons

Anton [14]

Easy,

100 gallons=800 pints

There are 8 pints to a gallon. Since 100 gallons is the same as 800 pints, that is larger than 400 pints, Witch is also 50 gallons.

So ill say 100 gallons are bigger. :)
