I am bringing 5 dozen cookies to my class. There is 27 students in my class. Only 18 students are here. If there is 9 students absent , how many cookies will each student get ?
So firts you multiply 5 by 12 and that equals 60, than you subtract 27 and 9 and that equals 18, also you will multiply 18 by 60 and that equals 1080, lat but not least you will need to add 9 cookies and then you have 1089, you can divid 1089 by 18 and that equals 60 cookies for each student.
I hope this the right answer and I hoped this helped.
Answer:
= - x^2 + 4x - 14
Step-by-step explanation:
(2x^2+6x−7)−(3x^2+3x−1)+(x−8)
= (2x^2+6x−7 ) −3x^2 -3x +1 + (x−8)
= (2x^2+6x−7 ) −3x^2 -3x +1 + x−8
= (2x^2+6x−7 ) −3x^2 -2x - 7
= 2x^2+6x−7 −3x^2 -2x - 7
= 2x^2+6x−7 −3x^2 -2x - 7
= - x^2 + 4x - 14
Answer:
(b + 7)(a + 4)
Step-by-step explanation:
ab + 7a + 4b + 28
separate the polynomial into 2 sections
(ab + 7a) (+ 4b + 28)
simplify each expression
a(b + 7)
4(b + 7)
you see that you have (b + 7) in both expressions. take that aside.
(b + 7)
you are left with a and positive 4. put these two together
(a + 4)
now put the expressions together
(b + 7)(a + 4)
