Answer:
10
Step-by-step explanation:
diameter is half of radius
It has one X-intercept. Graph it on Desmos and you can see the line, and then it becomes obvious it is one x-intercept.
Answer:
10
Step-by-step explanation:
20-(5×2)
5×2=10
20-10=10
The ratio would be 90pi/40pi.

Answer:
The area of DBE = 27 square units
Step-by-step explanation:
Area of ABC = 3 square units
In the figure, we can see that ABC was enlarged so that BDE is formed where side BD = 6 and AB was = 2
Hence ABC was enlarged 3 times its size.
We know by formula that:
Area of ABC = 1/2(base x perpendicular)
3 = 1/2(2 x p)
=> p = 3
As ABC was enlarged 3 times its size, the perpendicular of BDE must be 3*p
= 3*3 = 9
AREA OF DBE = 1/2(base*perp)
= 1/2(6*9)
= 27 square units
