Count the number of cubes in the first layer.

There is 16 cubes in the first layer.

Now divide the total number of cubes by the cubes per layer:

48 cubes / 16 cubes per layer = 3 layers.

What else would need to be congruent to show that ABC=DEF by SAS?

KonstantinChe [14]

Answer:

Step-by-step explanation:

SAS = side-angle-side

This means that, in order to prove that the triangles are congruent, they must have two congruent sides with the angle between them to the same.

We know that sides AB, ED, AC, and DF are all congruent as they all have a single mark through them. From this, you can conclude that the triangles already share two sides. All we need now is the angles in between to be congruent. This means that angle A and angle D need to be congruent.

I hope this helps!

2) Simplify.

$- 17y - 16z + 4$

So, therefor, the answer is -17y - 16z + 4.

What is the decimal expansion of the following fraction?

pickupchik [31]

You haven't shared a fraction. Please do that next time.

I checked and have found that 0.045 repeating over the 4 and 5 is equivalent to 1/22. Try dividing 1 by 22 to verify this.

So I infer that the fraction you haven't yet shared is 1/22.
