Answer:
-8x^2·y·z +3y·z^2 -4y
Step-by-step explanation:
It can be helpful to make sure the variables in each term are in alphabetical order. This makes it easier to see "like" terms. The variables in each term are ...
x^2 y z
y z^2
x^2 y z
y
Only the first and third terms are like terms, so those are the only ones that can be combined. Their coefficients are -7 and -1, so sum to -8. The combined term is of highest degree, so in standard form we list that term first.
= -8x^2·y·z +3y·z^2 -4y
Answer:
A: 5 behind the line
Step-by-step explanation:
You can make an equation: 8 - 6 - 4 - 9 + 6
Then you can solve it a little at a time:
8 - 6 = 2
2 - 4 = -2
-2 - 9 = -11
-11 + 6 = -5
Negative 5 is the same thing as 5 behind the line.

Answer:
Proved that DF = FE.
Step-by-step explanation:
See the given diagram attached.
In triangle Δ DEF, we have to prove DF = FE when ∠ 3 = ∠ 4.
The proof is like followings :
1. ∠3 = ∠4, Reason: Given
2. ∠1 and ∠3. Reason: They are supplementary.
∠2 and ∠4. Reason: They are supplementary.
3. ∠1 = ∠2. Reasons: Two Angles Supplementary to Equal Angles are Equal to Each Other.
4. DF = EF. Reason: Opposite sides of equal angles. (Answer)
