= 6x^2 + 3x + 10x + 5
= 6x^2 + 13x + 5
So the middle product is 13x.

Answer:
It bisects the triangle at the angle 90° . So that , we can say that an right angle triangle has only one line of symmetry which cuts triangle to two equal halves.
Answer:
left and right face
Step-by-step explanation:
the left side and the right side are exactly the same therefore it has the same cross section as it.
* just in case you have more questions about cross sections...look for the side that looks exactly the same as the cross section and that's the answer to the question if that makes sense*
Since an arithmetic sequence is a sequence of numbers and the difference of any two successive members of the sequence is a constant
So this question is arithmetic because it keep minus by 7
from 19 - 7 = 12
12 - 7 = 5
5 - 7 = -2
so common difference is -7
or you can check with arithmetic formular as
= 
+ (n−1)d
I will just put in the 4th term which is -2 and n will equal to 4
and is the 1st term which is 19
-2 = 19 + (4−1)d
-2 - 19 = 3d
d = 
d = -7
