Answer:
It took him 12 hours
Step-by-step explanation:
480 / 40=12
Area of trapezoid = Area of middle rectangle + Area of the right triangle + Area of left triangle
Area of rectangle= 5cm*9cm=45cm^2
Area of right triangle= 0.5* 9cm *2cm=9cm^2
For the left triangle, its an isosceles triangle as the base angles are equal,
so area of left triangle= 9*9*0.5=40.5cm^2
Area of trapezoid= 40.5+45+9= 94.5cm^2
Y+2=-4(x+1)
-4 x + -4
Y+2=-4x +-4
-2. +-2
Y=-4x+ -6
This is as far as I can get you too. I don't remember what to do after. Ask your teacher for help tomorrow. I hope I helped!
