Answer:
Use by Prime factorisation method
Answer:
12x - 73
Step-by-step explanation:
DFE + CFD = 12x + 7
DFE + 90 = 12x + 7
DFE = 12x + 7 - 90
DFE = 12x - 83
therefore
DFE = AFB ( vertically opposite angles are equal)
AFB = 12x - 83
Answer:
d
Step-by-step explanation:
To find this, use an equation with x to represent the smaller page number as your variable. set up the equation x(x+1) = 600. distribute the x to get x^2 + x = 600. subtract 600 from both sides so you have x^2 + x - 600 = 0. factor to get (x+24)*(x+25) = 0. so the two pages are 24 and 25

I found 608054144112
If the number isn't found by the given condition, write a variable to advance. but it is comfortable to solve if you follow them one by one
