Answer:
A. 5x^2 − 2x − 24 = 0
Step-by-step explanation:
height = 5b-2
b =x
We can rewrite the height as
h = 5x-2
We know the formula for area of a triangle
A = 1/2 bh
A =1/2 x * (5x-2)
Distributing the x
A= 1/2 (5x^2 - 2x)
We know A =12
12 = 1/2 (5x^2 - 2x)
Multiply each side by 2
12*2 = 2*1/2 (5x^2 - 2x)
24 = 5x^2 - 2x
Subtract 24 from each side
24-24 = 5x^2 - 2x-24
0 = 5x^2 - 2x-24
The correct answer is POMS

Answer:
i think its 2 my friend
Step-by-step explanation:
Answer:
S(-2,12)
y= -2(x+2)²+12
Location of coordinate axes:
y=0 → x= -2±√6 (-2-√6,0) (-2+√6,0)
x=0 → y=4 (0,4)
