2 is the unknown number.
Let x be the unknown number.
2x + 19 = 23
2x = 23 - 19
2x = 4
2x/2 = 4/2
x = 2
to check:
2(2) + 19 = 23
4 + 19 = 23
23 = 23
C
work:
75 is equal to 2x+15
75-15 = 60
60/2 = 30
x=30
now, let's recall the rational root test, check your textbook on it.
so p = 18 and q = 1
so all possible roots will come from the factors of ±p/q
now, to make it a bit short, the factors are loosely, ±3, ±2, ±9, ±1, ±6.
recall that, a root will give us a remainder of 0.
let us use +3.
well, that one worked... now, using the rational root test, our p = 6, q = 1.
so the factors from ±p/q are ±3, ±2, ±1
let's use 3 again
and of course, we can factor x²-x-2 to (x-2)(x+1).
(x-3)(x-3)(x-2)(x+1).
