I believe it's A. Sometimes you have to take an educated guess.
34.5=4h+7c
(34.5-7c)/4=h
Put h= (34.5-7c)/4 into another equation
30.5=8h+3c
30.5=2(34.5-7c)+3c
30.5=69-14c+3c
11c=38.5
c=38.5/11
Put c=38.5/11 into one of the equations
to calculate the h.
The vertex will be a maximum because the equation is negative, meaning the parabola opens downwards and will have a maximum point but no minimum point as it will get infinitely smaller.
Because it was the lat two choices and try using a punnett square
6 square meters.
Both of these two triangles are exactly the same, so we can find the area of one, the multiply it by 2.
The area of a triangle is calculated using the formula 1/2 * base * height. The base of each triangle is 3 meters according to the diagram, and the height is 2 meters. So, just substitute the values into the equation.
1/2 * 3 * 2
Now, just simplify the expression.
1 1/2 * 2
3
So, the area of each triangle is 3 square meters. Now, just multiply that by 2, so that we have the area of both of the triangles combined.
3 * 2 = 6
This means the total area is 6 square meters.
