Answer:
720
Step-by-step explanation:
6 x 120=720
Every 1 cm=120 km
So multiply both sides by 6 and you get
6 cm= 720 km
x+13÷2×2=4×2
x+13=8
x+13-13=8-13
x=8-13
x=-5
C
Divide 24 by 8 equals 3..
f(x) = (x^2 -4) ( x-5)
Here quadratic factor is ( x^2 -4) As x contains power 2
and linear factor is (x-5) as x contains power 1
