Answer: s(s+4)=7, 7 shelves
Step-by-step explanation:
I think it's easiest to find these type of answers by finding the common factors of a number. First 77, they are 1×77 & 7×11.so you can have 11 rocks on 7 shelves or 7 rocks on 11 shelves. The question states the number or rocks on the shelf is more than the number of shelves, so you must have 11 rocks on 7 shelves. You know you have 77 rocks, so the equation must equal 77. I plugged 7 in for s in the equations to determine the correct answer. 7(7+4)=77.
Coordinates of mid point=(x1+x2/2 , y1+y2/2)
=(5+7/2 , 13+5/2)
=(12/2 , 18/2)
=(6 , 9)
Use this formula to get coordinates of mid point
here the coordinates of mid point are (6,9)
(2,1) is the solution because its where they both intersect..
