3x-7>2
add 7 to both sides: 3x>9
divide both sides by 3: x>9
Answer:
100π
Step-by-step explanation:
Area of a circle formula: πr²
The radius would be half of 20 m
So the radius, r is 10 m
Plug that in
πr²=π·10²=100π
(18 - x)^2
If (a - b)^2 then the answer is a^2 - 2ab + b^2
18^2 - 36x + x^2
The answer is x^2 - 36x + 324

To multiply, you multiply across. So it would be 3×1=3 and 10×6=60
Which will result in
but in order to simplify it, you find a common factor. The common factor is 3. 3÷3=1 and 60÷3=20
The answer is
