Question

I don't understand plz help​

Answer 1

The answer to the question is 2A=3x

Answer 2

The equation that represent x, the height of the sign is;

`2a = 3x`

Explanation:

Given that the area of the triangular yield is A square feet

and it has a base length of 3 feet.

also the height is represented by x;

`b = 3ft \\ h = x`

Recall that the area of a triangle can be written as;

`a = (1)/(2) bh`

substituting the given;

`a = (1)/(2) * 3 * x \\ a = (3)/(2) x \\ 2a = 3x`

Therefore, the equation that represent x, the height of the sign is;

`2a = 3x`
