Answer:
C
Step-by-step explanation:
Given

The numerator is a difference of squares
x² - 16 = (x - 4)(x + 4)
=
← cancel the common factor (x + 4) on numerator/ denominator
=
→ C
Answer: 116 degrees.
Step-by-step explanation:
Interior angles of a triangle add to 180.
Knowing the first two angles are 36 and 28, you can subtract them from 180 to find the answer:
180 - 36 - 28 = 116
Answer:
FED ~ MLF
Step-by-step explanation:
∠L = ∠E
∠F = ∠F
Since both angles are congruent, that would mean all angles are congruent.
If all angles are congruent, then the triangles are always similar no matter the length of the sides.
Answer:
-4320t^2
Step-by-step explanation:
Use Pascal's triangle to figure out the variables.
In the 5th expansion, we see that the 4th term is:
10x^2 y^3
Plug in the values,
10*(4)^2 * (-3)^3 = -4230.
However, since the -3 in the original expression does not have a variable next to it, we do not include it in our answer.
Therefore, the 4th term is -4230t^2
