Answer: C
Step-by-step explanation:
Answer:
- 7
Step-by-step explanation:
21 = - 4x - 7
- 4x - 7 = 21
- 4x = 21 + 7
- 4x = 28
x = 28 / - 4
x = - 7
Answer:
The correct answer is last option
2n + m√n - nm
Step-by-step explanation:
It is given an expression,
4√n² + √m²n - √4n² - √mn²
<u>To simplify the expression</u>
4√n² + √m²n - √4n² - √mn² = 4n + m√n -2n -nm
= 4n - 2n + m√n - n√m
= 2n + m√n - n√m
Therefore the correct answer is last option
C the third one because it’s proportional to the tshirts
