(5x+5)(x+2) , is the factorised form. I'm pretty sure..I don't know for sure though.
Answer:

Step-by-step explanation:
The circumference of a circle is given by
, where
is the radius of the circle. Therefore, we can set up the following equation and solve:
(rounded to the nearest foot).
we know that
The <u>Triangle Inequality Theorem,</u> states that the sum of the lengths of any two sides of the triangle is greater than the length of the third side
so

we have

substitute the values
----->
-----> 
-----> 

therefore
<u>the answer is</u>
The value of x must be greater than 
Percent means parts out of 100
85%=85/100=0.85
'of' means multiply
therefor
85% of x equals 17 means
0.85 times x=17
divide both sides by 0.85
x=20
the number is 20
