Answer: 2 markers.
Step-by-step explanation:
1. You know that she gives 12 markers to Mr. Cooke, then the rest among is:
29 markers-12 markers=17 markers
2. She divides the rest among 5 other teachers and each one of them get the same number of markers. So, you need to divide 17 markers by 5 teachers as following:
17 markers/5=3.4 markers
3. But the number of marker each one teacher has can't be a decimal number, so this number must be: 3 markers for each teacher.
3. The number of markers that will be left over is:
17 markers-(5*3 markers)=2 markers

Answer:
7x^2+15x+31
Step-by-step explanation:
(3x+5)(x+5)
FOIL
3x^2+15x+5x+25
(3x^2+20x+25)+(4x^2-5x+6) = 7x^2+15x+31
