Answer:
both each side of each triangle is equal
use alphabets to mark each edge of the triangles and prove congruency
The vol. of a cube of side length s is V=s^3.
So, if the side length is 5a+4b, then the volume of the cube is
V(a, b) = (5a+4b)^3. This could, of course, be expanded, using the binomial theorem, but there's no point in doing so.
The appropriate compatible numbers to use to estimate would be 20(1/2)
estimated product is 10, took the quiz :)
Answer:
Second option:
Step-by-step explanation:
Let be "x" the number of candy bars Brady sold on Saturday.
For this exercise you need to analize the information provided in the exercise.
According to the information provided, Brady gets paid $2 for every candy bar he sells. This can be expressed as:

You know that Brady made a total of $90 on Saturday; this mean the product of
is 90.
Based on this, you can write the following equation that represents the number of candy bars Brady sold on Saturday:

Observe that this matches with the second option.
