Simplify (5+1)^2-(12+3^2)/3
lakkis [162]

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

If P is a point of symmetry, click on the graphic to find the figure that is symmetrical by P.
aleksklad [387]

Answer:

The third figure is the answer (Look to the attached figure

Step-by-step explanation:

* The point of symmetry means

- If a figure or graph can be rotated 180° about a point P

 and end up looking identical to the original, then P is a point

 of symmetry

- The same distance from the central point

  but in the opposite direction.

* Lets look to the four answers

- In the 3rd figure first line up can be rotated 180° about a point P

 and end up looking identical to the second line down, then P

 is a point of symmetry

- The same distance from the point  p

  but in the opposite direction.

* The figure show the answer

Write a two column proof
Annette [7]

4y=2x-10 and y=6

use the second expression to calculate the left-hand side of the first equation:

4\cdot 6 = 2x -10\\24 = 2x -10

Add 10 to both sides if this equation to get

34 = 2x

and divide both sides by 2

17 = x

this proves that x = 17, give the two initial equations
