Answer:
The first blank is 81
+9=x-1
The second blank is 9x+3=x^2-1
Step-by-step explanation:
For the first part, you must set up the equation (9x+3)^2 then you must multiply the exponent to the inside exponents 
+
next, simplify.
81+9=x-1
For part two, set up equation. 
Then simplify 9x+3= 
To find out the length of the third segments of the triangle, we can use this formula.
The, third length is very close to the 4. thus, the option (E) is correct.
We have two cirlces:
big circle⇒ diameter=24 ft
small circle⇒diameter 2 ft
Area of the ground covered by leaves=area of the larger circle- area of the small circle.
1) we calculate the area of the larger circle
Data:
diameter=24 ft
radius=diameter / 2=24 ft /2=12 ft
Area of the larguer circle=πr²=π(12 ft)²=144π ft²
2)We calculate the area of the small circle
Data:
diameter=2 ft
radius=diameter/2=2 ft/2=1ft
Area of the small circle=πr²=π(1 ft)²=π ft²
3) we calculate the area of the ground covered by leaves.
area of the ground covered by leaves=144π ft²-π ft²=143π ft²≈143*(3.14) ft²=
=449.02 ft²
Answer: the area of the ground covered by leaves is 449.02 ft².
There is multiple names it has, like for example “Zero” and in British English it is “nought” which is often used as an archaic word for nothing, I hope this help’s.
The answer is $1.75, im pretty sure
