Answer:
there are 48cubes fetted into a box
Lets check...
42/56 = 56/64
cross multiply
(56)(56) = (42)(64)
3136 = 2688...(incorrect)...these are not proportional
proportions are nothing but equivalent fractions
42/56 = 3/4
56/64 = 7/8
as u can see, they are not equivalent fractions...so they are not proportional
Answer:
x(3x+14)
Step-by-step explanation:
what do those terms share? they share the letter "x"
therefore we multiply x by 3x^2/x + 14x/x
3x^2/x = 3x and 14x/x = 14
A. 25mpg $13,000 B. 45mpg $25,000 15,000 $4
15,000/25 = 600, 600x$4 = 2400 15,000/45 = 333.3, 333.3x$4 = 1333.3
2400 = 1333.3x x= 1.8
