Combining like terms with rational coefficients
Answer:
- 0. 75 k - 2 .
Step-by-step explanation:
Given : 0.25k + 1.5 − k − 3.5
To find : Combining like terms with rational coefficients.
Solution : We have given 0.25k + 1.5 − k − 3.5.
On combining like term
0.25 k - k + 1.5 - 3.5.
- 0. 75 k - 2 .
Therefore, - 0. 75 k - 2 .
Using the pythagorean theorem
A)
2 + 3 = 4
5 = 4
since 5 is not equal to 4 so A is wrong
B)
8 + 9 = 17
17 = 17
so answer B) is correct
C)
25 + 36 = 64
61 = 64
since 61 is not equal to 64 so C) is also wrong
