Subtract negative = add
88 + 35 = 123
The solution is 123
1. 0 - 34 + 13 - 5 = -26.....26 ft below the surface
2. y = 15x + 50
220 = 15x + 50
220 - 50 = 15x
170 = 15x
170/15 = x
11 1/3 = x......he worked 11 1/3 hrs.......not sure about this...because it does not specify how many visits he made...but if this was just for 1 visit, then he worked 11 1/3 hrs
Answer:
To find the surface area of a pyramid, start by multiplying the perimeter of the pyramid by its slant height. Then, divide that number by 2. Finally, add the number you get to the area of the pyramid's base to find the surface area.
Step-by-step explanation:
Area of rectangle is given by:
Area=length×width
given that the area of our rectangle is 24x^6y^15. To get the possible dimensions, we shall factorize the area of our rectangle:
(24x^6y^15)
=(6x^6) by (4y^15)
or
=(8x^6) by (3y^15)
or
=(12x^3x^5) by (2x^3y^10)
