Answer:
180 - 92 - 41 = 47
There are not two similar congruent angle in the triangles.
Hope this helps!
Only one because there is one variable and the combined coefficients of x are non-zero.
(0.75(x+40)=0.70(x+20), 0.05x=14-30=-16, x=-320)
Answer:7x-29
Step-by-step explanation: simplify and open the brackets.remember that a letter and a number cannot be sumed up but can my multipled together
For this case we have the following functions:

We must find
when
.
So:

We apply distributive property to the terms within parentheses taking into account that:

We add similar terms taking into account that different signs are subtracted and the sign of the major is placed:

Thus, we have to:

Then, with x = 2:

Equal signs are added and the same sign is placed.
Answer:

In the attachement, there is what I came up with so far. I think that finding 'a' is non-trivial, if possible at all.
