The n subject of m = n² + 3 is 
How is n made the subject of m = n² + 3 ?
m = n² + 3
n² = m- 3

What does making n the subject mean?
- To make n the subject of the formula or equation, we must rearrange the variables in the formula or equation to have a single variable n that is equivalent to the other variables in the formula.
- The equation is then rearranged such that each term containing n is placed on the same side of the equation.
- If n appears in several words, factorization might be necessary.
- Just one n needs to be displayed at the conclusion to make it the subject.
- The result of square rooting a number or variable as an inverse operation may be positive or negative.

Answer:
8 Hours
Step-by-step explanation:
Since 4 painters painting one house takes 14 hours, then one person would take 56 hours to paint the whole house. Hence, 4 x 14 = 56. If 7 people painted the house, then 8 hours would be needed since 56 / 7 = 8.
4 people x 14 hours = House
56 hours = House
56 hours is required to paint a house.
7 people x H hours= House
7 people x H hours = 56
(7 people x H hours)/ 7 = 56 / 7
You divide 7 on both sides to isolate H on one side.
H hours = 8
So H = 8 which is the amount of hours needed.

Answer:
Correct choice is B
Step-by-step explanation:
Let x% be your final test score, then the average of all test scores is

Since you must have an average between 80% and 89%, then

X is measured in percent, then the greatest value of x can be 100%. You get that

"Will is twice as old as Jill."
Jill's age . . . . . J
Will's age . . . . 2J .
"Three years ago . . .
Jill's age then . . . . . J - 3
Will's age then . . . . 2J - 3
". . . Jill's age then was 2/5 of Will's age then."
J - 3 = (2/5) (2J - 3)
Multiply
each side by 5 : 5J - 15 = 2 (2J - 3)
Divide
each side by 2 : 2.5 J - 7.5 = 2J - 3
Subtract 2J
from each side: 0.5 J - 7.5 = -3
Add 7.5
to each side: 0.5 J = 4.5
Multiply
each side by 2 : J = 9
Jill is 9 y.o. now.
Will is 18 y.o. now.
