Divide both sides by 9 to go from this
9x > -18
to this
x > -2
On the left side the 9x becomes 9x/9 = 1x = x
on the right side we have -18/9 = -2
Answer is x > -2
Answer:
Step-by-step explanation:
Remember that
Area of Circle =

They told us that for this circle, the area is 
If you put it back into the formula for area of a circle we get:
Area of Circle =

Divide both sides by
.
144 = 
Now we want to solve for r (r = radius).
You need to square root each side


So now we know the radius,
metres
Also remember that
Diameter = 
So,
Diameter = 2 times 12 = 24 metres
Its a trick question. Its just 235 + 123 = 358. Find 358 on the number line and place a dot there, boom you did it on a number line.
