Answer:
Step-by-step explanation:
Given that an engine cylinder 13.7 cm deep is being bored such that the radius increases by 0.13 mm divided by min.
We convert everything in mm for uniformity
We have formula for volume as

Given that 
h is constant

= 6954.67 mm/sec^3
I’m pretty sure this is right:
Answer:
Step-by-step explanation:
I think you meant 3([7/5]x + 4) - 2(3/2 - [5/4]x). If that's the case, then identify the LCD: It is 20. Multiply both [7/5]x + 4 and 3/2 - [5/4]x by 20 and then divide the resulting expression by 20:
3(28x + 80) - 2(30 - 25x)
------------------------------------
20
Next, perform the indicated multiplication:
84x + 240 - 60 + 50x
----------------------------------
20
This simplifies to:
34x + 180 17x + 9
---------------- = ----------------
20 10
