Answer:
-4x^2, -3x, -5
Step-by-step explanation:
-4x^2 + 2x - 5 (1 + x)
-4x^2 + 2x - 5 + 5x
-4x^2 - 3x - 5
It's the first one because at Jefferson middle there are 24 students to 1 teacher and all you know about Hamilton middle is 12 teachers to 312 students
24•12= 288
So Jefferson will have 12 teachers for 288 students
9 × 9 = 81
9 plus itself 9 times equals 81
the nines table goes 9,18,27,36,45,54,63,72,81,90
To check the two numbers add up to 9 for 1-10 multiples
Algebra would be m × m =m^2
^means to the power and the 2 means we are doing it to the power of two [Also known as squaring]
This works because they are both the same number
