would the length of the wall be
1 answer:
Answer:
The length of the wall would be 12 cm
Step-by-step explanation:
we know that
On a blueprint with a scale of 1 cm = 4 ft, the length of the wall is 9 cm
so
The actual length of the wall is equal to ------> 9*4=36 ft
If the scale of the blueprint were 1 cm = 3 ft
then
The length of the wall in the new blueprint would be ----> 36/3=12 cm

The two partial products would be 990 *30 and 990 *7
You can also break it up into 900*37 and 90*37
2 / (z-5) = z / (0.5z^2 + 7)
cross multiply
z(z - 5) = 2(0.5z^2 + 7) =
z^2 - 5z = z^2 + 14 =
z^2 - z^2 - 5z = 14
-5z = 14
z = -14/5
