This is not an equation and thus cannot be solved for x. Ensure that you have copied down the original problem exactly.
If, on the other hand, you meant x + 2x - 3 + x = - 4, you do have an equation and can solve for x as follows:
4x - 3 = -4 => 4x = -1 => x = -1/4
The height of the triangle is 60cm, or 20cm+ 40cm.
The equation for area of a triangle is A=1/2bh
Your base is 30 cm height is 20cm.
A=1/2(30)(20)
A=1/2(600)
A=300cm^2
Your answer is 300cm^2

Answer:
A. 0 = −(x−6)^2+12
Step-by-step explanation:
The vertex form of a quadratic equation is ...
y = a(x -h)² +k . . . . . . for vertex (h, k) and scale factor 'a'
When the given vertex (h, k) = (6, 12) is used, we find the form of the equation to be ...
y = a(x -6)² +12
The ball will be on the ground when y = 0. Here, the vertical scale factor 'a' is -1, so the equation representing the ball being on the ground is ...
0 = -(x -6)² +12 . . . . . . matches choice A
