Answer:
are a, b, and c the options or are they different questions?
10 times 60 is 600 so the awnser 600
Answer:
42
Step-by-step explanation:
3 x {[(12-8) x 2] + [(11 - 9) x 3]}
12-8=4 and 11-9=2.
3 x ((4 x 2) + (2 x 3))
4 x 2= 8 and 2 x 3=6.
3 x (8 + 6)
8 + 6 is 14.
3 x 14 is 42.
Consecutive integers are 1 apart
x,x+1,x+2
(x)(x+1)(x+2)=-120
x^3+3x^2+3x=-120
add 120 to both sides
x^3+3x^2+3x+120=0
factor
(x+6)(x^2-3x+20)=0
set each to zero
x+6=0
x=-6
x^2-3x+20=0
will yeild non-real result, discard
x=-6
x+1=-5
x+2=-4
the numbers are -4,-5,-6
use trial and error and logic
factor 120
120=2*2*2*3*5
how can we rearange these numbers in (x)(y)(z) format such that they multiply to 120?
obviously, the 5 has to stay since 2*5=10 which is out of range
so 2*2*2*3 has to arrange to get 3,4 or 4, 6 or 6,7
obviously, 7 cannot happen since it is prime
3 and 4 results in in 12, but 2*2*2*3=24
therfor answer is 4 and 6
they are all negative since negaive cancel except 1
the numbers are -4,-5,-6
