it costs 8 dollars to rent a locker because
28x5=140
180-140=40
40/5= 8
We need two numbers that when multiplied will give you -40 and when added will give you -3:
(x+5) (x-8) this is your answer. And you want to know the process Here it goes. And attached is a chart I made you so you can visually see what this process is telling you:
1) identify a,b, and c in the trinomial ax^2 + bx+c (in your case it's 1x^2-3x-40= x^2-3x-40)
2) write down all factor pairs of c (numbers that multiplied produce -40)
3) identify which factor pair from the previous step sums up to b
4) Substitute factor pairs into two binomials
Answer: x=5
5x-3 (x-3)= -6 +6x -5
5x -3x +9 =-6 +6 x -5
ANSWER: 11, 12, 13
3 consecutive integers:
"Sum" means Add
Combine like-terms
Solve for X
Subtract 3 from both sides
Divide by 3 on both sides
11 + 1 = 12
11 + 2 = 13
