Answer:
-40
Step-by-step explanation:
Let's input x into all of the slots.

Now, let's solve!


So, the answer is -40!
triangle XBR is similar to triangle YNJ.
Similar triangles are triangles with lengths in proportion, and congruent corresponding angles. When naming a similar triangle, the letters or vertexes are listed in a certain order. For instance, angle X is the same as angle Y so those two letters have to be in the same position. In this case, they are both the first letters. Angle B is congruent to angle N and angle R is congruent to angle J so they will also have to be in corresponding positions. The side lengths are extraneous information that can be used to check, but otherwise I would just stick with angles. Hope this helps!
Answer:
11x^4
Step-by-step explanation:
The double negative automatically makes something positive. Your new expression is 5x^4 + 6x^4.
The only other thing you need to do is combine like terms by adding them together.
11x^4
The answer is A because we simplify the 7 b by subtracting 6 b which gives us 1 b but in this case it will just be B and then we add 7c
