Answer:

x = 5

Step-by-step explanation:

You first have to multiply 3 by x and 2, and you would get 3x and 6. 3(x + 2)=3x +6

Then you have to move the 6 to the other side and it will become negative. 3x= -6 +21

Then you subtract 21-6 to get 15. 3x = 15

Then you are left with 3x = 15.

Divide 3 from both sides and you get x =5.

Answer:

A. x^2 = (4x - 1)^2 + (6x + 7)^2

Step-by-step explanation:

The question seems to be incomplete. However, we'll make the following assumption.

Opposite = 6x + 7

Adjacent = 4x - 1

Hypothenuse = x

Pythagoras theorem states that:

Hypothenuse^2 = Opposite^2 + Adjacent^2

Substitute values for Hypothenuse, Opposite and Adjacent.

This gives

x^2 = (6x + 7)^2 + (4x - 1)^2

or

x^2 = (4x - 1)^2 + (6x + 7)^2

From the list of given options.
