Answer:
6
Step-by-step explanation:
The sum of the roots (y-intercepts) of the polynomial is the opposite of the ratio of the linear term coefficient and the leading coefficient.
b + c = -(-6/2) = 3
The x-intercept is the constant: a = 3
Then the sum a+b+c is ...
a + (b +c) = 3 + 3 = 6
_____
<em>Additional comment</em>
The factored form of the polynomial for the given intercepts will be ...
x = 2(y -b)(y -c)
and the expanded form of that is ...
x = 2y^2 -2(b+c)y +2bc
The y-coefficient is ...
-2(b+c) = -6
b +c = 3 . . . . . . . divide by -2. This is the result used above.
We show the graph so you can add up the values of the intercepts to see that the sum is 6.
Answer:
We divided the figure into 1 triangle and 3 rectangles (as shown in attached pic).
Adding up the area of them, we get the total area:
A = area of triangle + area of 3 rectangles
= base x height/2 + length1 x width1 + length2 x width2 + length3 x width3
= 6 x (2 + 11 + 5 - 4 -3)/2 + 2 x 2 + 11 x (5 + 2) + 5 x 9
= 159 (m2)
Hope this helps!
