1: x=-2 2: x=-3 i did send a pic hopefully you can see it is not I will type in comments how to solve it
We know that
area of a circle=pi*r²
for r=2 km
area of a circle=pi*2²-----> 12.56 km²
if 360° (full circle) has an area of---------> 12.56 km²
45°---------------------------------> x
x=45*12.56/360-----> x=1.57 km²
the answer is
1.57 km²

The slope of y=9x is 9/1 which simplifies to 9
The slope of y=10x-2 is 10/1 which simplifies to 10
You can do addition and substraction operations with polynomials similarly as with simple real numbers.
First of all you have to open brackets and then you can add numbers (-7-4=-11). Then the result is following:
