To make this easier to read, I'll be substituting 1/2 for .5; they mean the same thing, but it's less confusing to type it in its decimal form.
7x + .5 + 6x - 9.5
Combine like terms (x's can be added together, and so can reg. numbers)
(7x + 6x) + (.5 - 9.5)
13x - 9

The answer maybe C ) cylinder =200pie and cone = 80pie
Convert to vertex form
or easier
for y=ax²+bx+c
the x value of the vertex is

and the y value is found by subsituting the x value in for x
so
y=1x²+4x+11
a=1
b=4
the x value of the vertex is

the y value is found by subsituting -2 for x
y=(-2)²+4(-2)+11
y=4-8+11
y=7
the vertex is (-2,7)
Answer:
3/49
Step-by-step explanation:
The area of a rectangle is found using A = l*w. At the park, it measures A = 49*25 = 1,225 yards².
On the map the area is A = 3*25 = 75 inches².
The ratio of the area of the map to the area of the park is found by placing 75 ovre 1,225. Then simplify if possible.
