An expression of more than 2 terms
Answer:
251,734.
Step-by-step explanation:
The Winding river is modeled by r(x)= 
As bridges will be built along x-Axis to cross the river.
so,the bridges work as a tangent to river.
r'(x)=
So , r'(x)=0
→=0
→3x²+6 x+ 2 x+4=0
→3 x(x+2)+2(x+2)=0
→(x+2)(3 x+2)=0
x=-2, x= -2/3
As there are two values of x, from where we can draw tangents or bridges to the river.So there are maximum of two bridges that we need to built.
<span>The first choice is correct.
Explanation<span>:
The formula for slope is m=(y</span></span>₂<span><span>-y</span></span>₁<span><span>)/(x</span></span>₂<span><span>-x</span></span>₁<span><span>). Once we find the slope using that formula, it goes in place of m in y=mx+b.
We do not yet have the y-intercept, but we can use one of the points to find it. We substitute the x-coordinate of one point in for x and the y-coordinate of the same point in for y; then we solve for b. This gives us the y-intercept.</span></span>
