Answer:

29

Step-by-step explanation:

Simplify the expression (5+1)^2-\dfrac{12+3^2}{3} step by step:

1.

(5+1)^2=6^2=6\cdot 6=36

2.

\dfrac{12+3^2}{3}=\dfrac{12+3\cdot 3}{3}=\dfrac{12+9}{3}=\dfrac{21}{3}=7

Now,

(5+1)^2-\dfrac{12+3^2}{3}=36-7=29

Marat540 [252]

Answer:

(1) 1 and 7

Step-by-step explanation:

Hello!

We can solve by isolating the variable.

<h3>Solve</h3>
  • 3(x - 4)² = 27
  • (x - 4)² = 9
  • √(x - 4)² = √9
  • (x - 4) = ± 3
  • x = 4 ± 3

There are two solutions, 1 and 7.

The answer is option 1: x = 7, x = 1.
