The line crosses (1/2,0) and (0,4/7)
Let m be the slope of this line
● m = [0-(4/7)]/[(1/2)-0)]
● m = (-4/7)/(1/2)
● m = (-4×2)/7
● m = -8/7
So the slope of this line is -8/7
Use the equation for the area of a triangle:

where A = area, h = height of the triangle, and b = base of the triangle.
You know that h=18m and A=99

. Plug those values into the equation and solve for b, the base.
The base is 11m long.
7.05 is the correct answer
Yes
remember that an odd power of a negative is negative
(-1)(-1)(-1)=(-1) tiat is negative
alsoo remember that ∛(ab)=(∛a)(∛b)
so
∛(-64)=(∛-1)(∛64)=(-1)(4)=-4
