Answer: A) 3j + 5n
Step-by-step explanation:
Hi, to answer this question we have to write an expression using the information given:
The product of the number of hours that Jane worked per day ( j ) and the number of days worked (3) plus the product of the number of hours that Noah worked per day ( n ) and the number of days worked (5) must be equal to the total number of hours worked by both.
Mathematically speaking:
3j + 5n
MASS*GRAV*HEIGHT=PE
MASS=3
GRAV=9.8
HEIGHT=4.5
3*9.8*4.5=132.3
POTENTIAL ENERGY= 132.3
