10x - 8xy - 3xy
= x ( 10x - 11xy )
Answer:
Option b. sum of all areas of faces
Step-by-step explanation:
we know that
The surface area of the prism is equal to the area of its bases plus the area of its four rectangular lateral faces
so

where
B is the area of the base
P is the perimeter of the base
H is the height of the prism
therefore
sum of all areas of faces

Step-by-step explanation:
Answer:
3
Step-by-step explanation:
The scale factor of ABC to DEF is the number you need to multiply a corresponding side of ABC to get one of DBC. We are given the two triangles are similar, so we can say that sides AB and DE are proportional. We are looking for the number we need to multiply AB by to get DE. From this relation, we can get the equation:
AB * x = DE
where x is our scale factor. We can substitute in the values of AB and DE, and solve for x:
5x = 15
x = 3
Therefore, the scale factor is three. This means that you can multiply any side of ABC by 3 to get a side of DEF.
