The area including cutout is 15*8=120
the area of cutout is 5*5=25
120-25=95 cm²
Answer:
I think y= -1/3x
sorry if wrong
Step-by-step explanation:
Answer:
9x+5y=-45
Step-by-step explanation:
To write the equation of a line we must have a slope and a point. To find the slope we use the slope formula and substitute (x,y) points in it as shown below:

Now that we have the slope, plug in the slope and choose one point to plug into the point slope formula. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.
(y-0)=-9/5(x--5)
y=-9/5(x+5)
y=-9/5x-9
Now convert to standard form, Ax+By=C.
y=-9/5x-9
9/5x+y=-9
9x+5y=-45
Answer:

Step-by-step explanation:

Distribute x through the parentheses
