1. Solve 3x + 3 =21
sveta [45]
1.

3x + 3 = 21

3x = 21-3

3x = 18

x = 18/3

Therefore,
x = 6


So option ( B) is the correct one.


2.

\frac{3x}{2}  - 4 = 16 \\  \frac{3x}{2}  = 16 + 4 \\  \\  \frac{3x}{2}  = 20  \\ 3x = 20 \times 2 \\ 3x = 40 \\ x =  \frac{40}{3}  = 13 \frac{1}{3}


Therefore option (B) is the correct one here too.

Simplify the polynomial (4n² + 3n – 5) − (2n² + 3n<br> -<br> + 6)
Veseljchak [2.6K]

Answer:

2n² + 1

Step-by-step explanation:

Given polynomial:

(4n² + 3n – 5) − (2n² + 3n - 6)

Solution:

Removing parentheses,we obtain

  • 4n {}^{2}  + 3n - 5 - 2n {}^{2}  - 3n + 6

Combine like terms:

  • 4n { }^{2}  - 2n {}^{2}  + 3n - 3n - 5 + 6
  • 2n { }^{2}  + 0 + 1
  • \boxed{2n {}^{2}  + 1}

Done!
