13. What is the result of adding 5.4a + 7.1 and -1.28 - 6.3?
1 answer:
Answer:
C. 4.2a + 0.8
Step-by-step explanation:
Given:
The two binomials given for addition are:
and
Now, adding both the binomials, we get:
Distributing the positive sign inside the second binomial, we get:
Now, combining like terms using the commutative property of addition, we get:
Simplifying the above expression, we get:
Therefore, the resulting addition of the given binomials is
Hence, option C is the correct answer.

Hey there :)
We know the distance formula is:
D =
1) Coordinates are: ( -10, -5 ) , ( 8 , 5 )
↓ ↓ ↓ ↓
x₁ y₁ x₂ y₂
We plug in the values
D =
≈20.59 ≈ 20.6 (nearest tenth)
We do the same for the rest
2) Coordinates are ( 10 , 0 ) , ( -2 , 1 )
D =
≈ 12.04 ≈ 12.0 (nearest tenth)
3) Coordinates are ( 4 , 8 ) , ( 7 , -8 )
D =
≈ 16.27 ≈ 16.3 (nearest tenth)
4) Coordinates are ( -10, -4 ) , ( 8 , 8 )
D =
≈ 21.6 (nearest tenth)
5) Coordinates are ( 6 , -3 ) , ( -8 , 9 )
D =
≈ 18.4 (nearest tenth)
You can find the matching below :)
