Answer:

X=13

Step-by-step explanation:

So if ΔABC ≅ ΔDEC, then that means that ∠B is ≅ ∠E. Therefore you would write the equation 3x=6x-39 and solve for X to get 13.

a rectangular prism measures 2 in by 4 in by 8 in what is the side length of a cube with the same volume
Umnica [9.8K]
<h3>✽ - - - - - - - - - - - - - - - ~<u>Hello There</u>!~ - - - - - - - - - - - - - - - ✽</h3>

➷ First find the volume of the rectangular prism:

2 x 4 x 8 = 64

Now you need to cube root it, this would be because all lengths of a cube are equal:

\sqrt[3]{64} = 4

The side length would be 4 inches.

So,

In order to find numbers that are in between 3/8 and 6/7, Lucy must make common denominators first.

LCM of 8 and 7: 56

Multiply each fraction by the appropriate form of 1:
\frac{3}{8} *  \frac{7}{7}\ AND \  \frac{6}{7} *  \frac{8}{8}

\frac{21}{56}\ AND\  \frac{48}{56}

We can immediately see that any fraction with a numerator between 21 and 48 and a denominator of 56 will fit into the criteria Lucy needs.

The correct option is B.
